My girlfriend is so mean to me. Everything I say to her she snaps at me, We don't have sex, any money that she gives me I have to pay back. We have four foster kids(HER FAMILY) and she makes no effort for private time. She tells me she's attracted to me she is just under stress. She talks to me like a child and I am not even being myself around her because I'm always trying not to piss her off. I want to leave but she begs me not to go. I don't get ANY affection not a hug, not a kiss on the cheek NOTHING unless I initiate it and then she acts like I'm bothering her. Finally if I complain, she becomes the victim and I'm wrong. Am I going crazy? I am nothing but nice to her almost to the level of kissing and yet she is still so mean. What am I supposed to do?

Sounds like my boyfriend, except I am the one with the four kids. Why don't you leave?
Why stay because she begs you? She can't have it all her way just because she wants it that way. You really should plan on moving out and never looking back. I know its easier said than done. But think about months/years down the road and you are still in the same situation. Pleasing her and wasting your life and chances at happiness.
