stupid or what???

I don't actually know where to start with this one. I have been with the same guy on and off for the passed 11yrs, he was my boss when we first started going out. I was 18 he was 28, now that we're older things have got a lot better and I feel he's growing up now he's nearly 40 lol. well that's what I thought until me and him got into a conversation about the pill and missing it or if your sick you count it as a missed pill if it's within a few hours of taking it. Now this brought us on to talking about me having a miscarriage witch he said I never told him about now he would remember this if he wasn't always drunk. But anyway that's not the point the thing that really pissed me off was that he said the only think he's remembers is when he took me for the morning after pill and a took the huff and didn't speak to him for days n walked about crying, witch once again is total bull yes he took me for the morning after pill but the time he's talking about is when he bullied me into having anabortion told me if I had the baby he would fire me and he would never speak to me again and if the kid ever went looking for him than he would slam the door in its face, so I want and got the abortion but the night before a txt him n asked if he would phone me as I was scared n didn't have anyone else to talk to. He told me I don't have anyone either and he was going out so not to bother him again. The day after the abortion he picked me up for work a couldn't even look at him yet all he could say to me was what happened not even r u ok he didn't give a fuck. The worst day of my life n he pretends it never even happened n am the one talking shit. Do we think it's time I finally walk away for good?????
