my boyfriend wont move in with me until i prove Im not cheating

I felt so sorry for this woman today, she appeared very browbeaten and low.
Her boyfriend is from my experience an aggressive psycho and I wish I could warn her, what she is going through now is nothing compared to what she will likely go through..... all I can do is wish her the best of luck and hope she is the one that can make changes because I certainly couldnt and thankfully got away in time, but my self esteem was once low and people like him see you coming a mile off...... please please go carefully and best of luck and I sincerely hope you can find some hapiness
