In a relationship, whether, you are a boy, or a girl, you always want to try to please your significant other, trying to be the perfect piece to their puzzle. However, the more time you spend with your significant other, you begin to doubt yourself, doubting that maybe you just aren't the one for him.

As badly as you want to be the one for him/her you feel some sort of way, like you believe that they could do better without you, that you are the one holding them back from being the best man/woman they can be. You feel as though you may be the one weighing down the relationship. You just want them to be happy and just want the best for them. You are hopeful that you're the best for them, but for some reason, deep down, you feel that they should be with someone else, that they deserve someone other than yourself.

Perhaps it may be because you feel that you can't be loved. Perhaps you have low-self esteem and may feel unworthy of love. You think: how can someone love you so much, when you can't even stand yourself? They must/should be with someone else because you believe that you can't be that amazing for them to want to even want you around, so you find anything to believe that they would be better with someone else. I

t may be something they casually say that may set you off to believe that they would be better of without you. It hurts because you want to be the woman/man of their dreams, to hopefully maybe one day to be the only girl they last with, but you can't help but believe that you aren't the one for that. You observe them, hear their words, watch their actions and all you can think about is that they should be with another girls that wants all the things they want in life.

Perhaps, the reason why you're overthinking and over-analyzing is because deep down you are scared.You want to believe all the insecurities you are feeling because you are afraid you will end up getting hurt, so you begin to build a wall up so they don't hurt you first. The problem is that you find yourself falling deeply in-love with them and yet your defense mechanism is to runaway before anything happens.

In other words, you want to pull back before they realize you aren't the one for them. Maybe it's because of you past relationships that make you feel like this. You may have learned early the some relationships just don't workout. You feel that this could be another one that is only here for the time and will be gone before you know it. Maybe you're trying to save yourself before another heartache. Maybe you want to be prepared before the worse happens.

Or perhaps, your past is ruining what your present could be. Maybe you realize that for once you finally have someone amazing, someone that respects you, supports you, and loves you with and without flaws. And maybe that is what scares you the most- that you finally have something good and that it may come crashing down before your eyes.
