I need help.

Ladies i know y’all are not psychologist or anything but i need some advice. me and my boyfriend have being together for almost two years he is a really nice guy smart and he respects me a lot he doesn’t talk to any other girl or anything. But we always argue so much for stupid things i don’t know if it is because of my attitude or what we both are tired but its hard for me to change we always end up crying mostly him because he wants me to stop treating him bad but its hard for me to do so and i don’t even know why because i love him every-time we argue and cry we always tell each other that it won’t happen again but the same thing keeps happening. So what should we do? Should we break up ? 😥 i suggest him that we can start going to church to feel better and so our relationship can get stronger but we haven’t go. I really love him and I don’t want to loose him but i think I did already...
