I'm living with a woman whom I used to be engaged to. We've done a lot of fighting from the start because her behavior was sort of shady. I never really felt like I was getting the whole truth. I never actually caught her doing any thing but I was suspicious. We got into a big fight 2 weeks ago and she moved into spare bedroom. She basically acts like she hates me now. She won't talk to me and tries to do every thing she can to be mean and hurtful now. This really bugs me because just a month ago we were in love and going to get married. I really love her and want to reconsile but she says its over.I'm just stunned at how easily she can throw it all away! I think she's seeing someone but she won't admit to it. What should I do to try and get her back? How she just stop loving me basically over night?
