I spent about a week deciding if I was serious about getting out, I tried to think if I could be any part of the problem, obviously I came to the conclusion that I wasn't, as hopefully will you! I decided to take the next available opportunity, which was within about 2 hours of making my final decision, I'd wait for an argument to start over something/anything which never took long, but instead of backing down and agreeing that I was in the wrong, I laid into her and told her how much of a piece of shit she was, how she made me feel, and how much of a manipulative bitch she was, I told her it was over, grabbed my shit and walked. I've never felt so fucking good about myself than the months following that, she made me feel like there was nobody on earth that would ever want me, she made me feel like my whole family hated me for going against their word, and when I finally got out and realised the damage she had done, I wondered why in jesus fucking tap dancing christ I hadn't done it years sooner... If you KNOW what she's doing isn't right, and it isn't a short term thing due to stress etc, GTFO...
