I've Had Enough of My Boyrfirend's Mother...

It's not that I don't like her or at least try to like her. But she just gives me every reason not to. She is so old fashioned. PDA is not acceptable. She once refered to my boyfriend and I to my mother as really good friends. Hello, we've been dating for almost a year and a haLf. I seriously cannot take it anymore. She is really annoying and can just get the best of my nerves. She asks me the same question like three times in a row and the answer is always the same. It's ridiculous. And she is so guillable. She will believe anything, I just feel sorry for her that she can be that stupid. I try so hard to put these feelings behind for my boyfriend's sake, but I don't think I can take it anymore. I;m not even allowed to stay at his house on the couch, in the basement, while he is in his bedroom sleeping two floors up. She just doesn't like the idea. Once i left my car at his house overnight bc i was too tired to drive home, and she flipped the next morning. She questioned my boyfriend about the sleeping arrangements, and when he said i wasn't there she asked where i was hiding, and preceded to look throughout the house. I mean seriously I don't know what to do. She is driving me crazy, and I don't know if I can keep up my "act" around her anymore. She is probably the only thing that would drive me away from my boyfriend. I love him and i know he loves her too, and I don't want to upset him with these feelings I have.
