can someone tell me.

How can I have gotten to the point where I can not even remember why we started this relationship? we shouldnt be used to fighting. But we both are. && that cant be good. This is too much to fathem and I am too young to stress so much over a relationship. All I know is that someone or someone has to change or this is not going to end well. && id hate that. I love her so much. But I have to love me more. At some point. right? I hope this turns around.
