<human>: Hey all.

I've got something on my mind that is killing me. I've been together with my girl for almost 2 years and I feel there is nothing left to gain. 

We met while we both were in college and now we live together and bought a car a few months ago(stupid I know, but we both needed it). 

The thing is, I can't say that I love her anymore. We fight like crazy for weeks on end, only to have about a week of peace and quiet before you can feel the tension slowly building up again. I feel as she is trying to change who I am and I'm too much of a coward to stand up for myself. 

The girl is hell-bent on me, and is almost suffocating me with love, when she crazy-aggresive about thing she thinks I'm suppose to do. All my friends and family loves her and think she is the best thing that ever happened to me. 
Though she is a freaking werewolf, only to shift and turn bat-shit-crazy when we are alone.

Can you summarize the given text in a few sentences?
<bot>: My question is; Has anyone else been in a similar situation? When you have lived together with someone and realized you have to get out, and get out quick?
