Adjustment of Status - I-485

Hi guys. It's been 15 months we are married. I filed my paper work almost a year ago and no interview yet. The past two months are the worst time since we lived together(year now). We argue so much for nonsense stuff. She even put her hands on me couple times but I never call the cops for any report. Now she accusing me of cheating without any proof and asking me to move out because I left my house and move to hers. I'm not cheating, I don't even have time for myself. She constantly going trough my phone but never found anything. It's just so much going on. Her job is not steady and I'm the one who provide everything to support her and her daughter. I work a lot so when I come home I want to relax, not argue over nonsense stuff. I'm getting tired and can't take it anymore. Now I'm really thinking to move out so my mind can be peaceful. We both agreed to leave separately now to see if things going to get better. My only issue is that my case is still pending and I want to move out. Any suggestions will be appreciated
