You’ve probably heard of the seven deadly sins (greed, lust, wrath, etc.) With relationships, however, that number is a steady 18, in no small part due to the fragile nature of our romantic entanglements.

Most of the sins listed below have a specific cause and effect, and we exercise at least a portion of these deadly errors. As a result, it can be nearly impossible for us to avoid committing these sins once in a while. Still, you can make a substantial effort toward recognizing these sins and preventing them from becoming a lifestyle that will undoubtedly ruin your relationship.

1. Negativity

Think about it. Do you like being around a negative person? Maybe you’re the one who is sick of the other person constantly being cynical and unenthusiastic about things that make you happy. No matter who is on the receiving end, negativity that has gone unchecked will ultimately sour the romance.

2. Indecision

99.99% of girls claim they like a guy with confidence, and for a good reason. Guys are also far more comfortable being with someone who is able to show assertiveness when the situation calls for it. Though you don’t have to have an over-inflated ego, it’s essential that you’re able to make decisions and stick with them, especially when it counts the most.

3. Insecurity

Related to indecision, insecurity is a sin that can lead to major relationship problems, such as jealousy and envy. If you’re constantly filled with self-doubt, then your partner may start to have doubt in you as well. Sometimes, our insecurities can be brought on our exasperated by our partner, so in these cases, the best fix is for you to communicate openly about your insecurities with the person you’re dating.

4. Belittlement

Constantly berating and bad mouthing your boyfriend or girlfriend is a huge relationship transgression, especially if you’re doing it behind their back. It’s normal for couples to playfully banter, but this can lead to a dynamic that is built on unhealthy habits, like competition and intimidation. Worse, this can lead to serious issues, such as verbal or physical abuse. If you’re openly and harshly criticizing your boyfriend or girlfriend on a regular basis, then you need to make some serious changes or call it quits before it gets worse.

5. Clinginess

Not being able to give someone space is one of the most common relationship sins, mostly because it’s rooted in external problems like dependence and (sometimes) immaturity. It can be difficult to recognize when you’re committing this sin, as it tends to happen when you have genuine intentions, but you have to read the signs. If your partner is complaining or avoiding you because they can’t seem to find time for themselves, then your relationship is headed for trouble. Additionally, if this is a persistent problem for you, then it may be better for you to take a break from dating.

6. Being Disagreeable

Have you ever talked to someone who disagreed with you by default? We like to do this with our parents or individuals we’re initially skeptical of, but it really doesn’t settle well when we do this in our relationships because…well, it’s really annoying. You don’t have to agree with your partner 100% of the time, but you need to make it clear that you’re supportive of them. Before you agree or disagree, hear them out and be empathetic toward what they’re experiencing. Otherwise, they’ll be tempted to go to someone else.

7. Neglect

This can be a very bad sign for a relationship because it typically means that one person (or both) is not interested or inclined to be involved with the other. It should be obvious that ignoring or being indifferent to your partner is going to lead to conflict and/or will make them want to end the relationship, so if that’s not what you want, take a look at why you’re being neglectful in the first place and fix it.

8. Not Listening

Maybe you’re not neglecting them completely, but you do have a hard time listening to what they’re saying. It’s easy to be a good listener during the first stage of a relationship because the information is new, and you’re infatuated with this person. Eventually, it gets harder, but that doesn’t mean good listening skills aren’t expected of you. Men tend to be the usual suspects for bad listening skills, but women can be just as bad. No matter what the reason is for your difficulty in this area (mine is that I have a deaf ear), find a way to start correcting this sin before it leads to bigger ones, like neglect.

9. Bossiness

Being too controlling in a relationship is a dangerous problem because it usually starts out innocently. The more domineering person will step up and make the decisions because that is the nature of their personality, and the other person may be more than fine with this. Down the road, however, this level of bossiness can become too much for the other person to bear once they realize they don’t make enough of their own decisions.

10. Resentment

It’s easier to forgive than forget. When we make a sacrifice for someone, or if we are wronged, resentment starts to grow, especially if we don’t feel validated and affirmed by our partner. The major problem with resentment is that it leads to a lack of empathy, which can lead to cheating and insecurity. Also, resentment can be difficult to overcome if it has been bottling up for a long time, so if you want your relationship to last, you need to be open about how you’re feeling toward the other person before it overwhelms you.

11. Pedestal Building

Most people get pretty excited when they find someone to love, but this can lead to unrealistic expectations. If you put someone on a high pedestal, it’s that much more painful when they make a mistake and fall. The root of the problem is trying to fully know someone before you have all of the facts. Pace yourself, and your expectations, so that you don’t make your partner feel like they can’t live up to who you see them as.

12. Ingratitude

This is a simple one, but it’s a cinch to commit. Over time, it gets challenging to show our appreciation and gratitude for our significant others, and this can ruin a healthy relationship. Sure, you can verbally thank someone for what they’ve done, but the best (and lasting) types of gratitude are done through actions. Doing this may actually prevent many of the other sins on this list because they typically start with simple appreciation.

13. Stubbornness

Not only are you disagreeable, but you’re stubborn to the point where you never make compromises. If you’re the person who is a statue, keep in mind that faltering doesn’t show weakness or make your relationship flimsy. Instead, it shows that you’re willing to trust the other person and meet them halfway. What’s really stubborn is how detrimental this habit is to your dating life.

14. Narcissism

Being self-obsessed is another “root” sin that leads to the other sins on this list, especially neglect and not listening. Symptoms of narcissism are that you force yourself to the be the center of attention (or the conversation), you quickly bail if you’re bored and you are consistently looking for praise and affirmation. To be honest, most people under 30 are pretty narcissistic, including me, but we can make great lengths toward curbing our self-obsession with genuine care and compassion for the people we love.

15. Manipulation

A great way to lose someone’s trust is to manipulate them. Obviously, outright deception and dishonesty for our own gain is a common method of manipulation, and you probably know this already. But manipulation can start in your other relationships as well, making it a tricky habit to stop. Acknowledge how you treat the other women/men in your life (like your parents). If you tend to mislead them for your own needs, then chances are that you’ll do the same thing in your dating life. Eventually, you’ll probably get caught, and your relationship will suffer.

16. Duplicity

The opposite of integrity is duplicity. This means that you’re one way with a group of people and another way with everyone else. When dating, we do this during the “impress me” stage. When we first meet someone, we want them to like us, so we put on a mask to accommodate them. The problem is that our true colors come out eventually, and our duplicity can lead to a souring of the relationship. It’s okay to make yourself seem more flattering when you first meet someone, but avoid being fake and dishonest about your values and personality. It’s more beneficial in the long run.

17. Monotony

There are plenty of ways for your relationship to fall into a rut. Routines make our daily lives manageable, but the side effect is monotony, which can make both you and your partner bored with each other. The good news is that it isn’t hard to get out of the rut. Inject spontaneity into your relationship whenever possible, and be the person who makes an effort to try new things when you have free time. If you wait for the other person to do this, you might be disappointed.

18. Infidelity

I saved this for last because it’s one of the biggest sins you can commit in a relationship, and it comes about from some or a combination of the sins above. Understand that infidelity isn’t usually something that happens on a whim or out of nowhere. It happens when the other person is neglectful, manipulating, disingenuous or unwilling to compromise. That’s why one of the best ways to prevent cheating or being cheated on is to avoid these deadly sins at all costs.
