Lately I've been feeling like I'm projecting my own infidelity onto my girlfriend. It hurts to suffer from the constant jealousy.
Well are you being unfaithful to her?
I'm afraid that I might cheat on her if I don't end it right now.
If you are afraid that either of you will cheat, there is something wrong in the relationship. You should talk this out as a couple before one of you decides that breaking up is the best thing to do.
What! How can you say that? You are just saying that because you are infatuated with me.
I'm not, I'm just merely trying to give you the best advice I can in the situation. But if you're having these thoughts and you don't think that you can fix the relationship, then breaking up would at least be a better option than cheating.
