I know. I gave up on this dream a long time ago, and just tried to emotionally distance myself from her. I stopped asking her to do things with me, because she always had some excuse not to. I just did my own thing. At one point, I took my son on vacation and she told me she would probably be dead when I got back. She wasn't dead, and we had a good time on vacation. She acted like I had done some terrible thing by wanting to go one vacation. She even told my son I would probably leave him in the hotel room by himself, so that he was terrified of going. That's the sort of stuff she does to me.
She called me at lunch time today and I just couldn't talk to her. She'll probably do something insane now, like not speak to me for weeks, follow me around, or something similar. Or else she'll feel repentant and buy me something, usually something expensive, or she'll do all sorts of things to make me feel better. It doesn't work anymore though. I've caught on. I caught on ten years ago when I was nearly kicked out of school because she didn't pay my tuition. That was the last time, I let her stay in charge of my bills. I paid for the rest of college myself.
