I have been with my fiancé for about a year and a half. He cares about no one but himself. He is a liar, cheater and a thief. He suckered me in his world and I believed everything he said. Left my home, that I can't go back to now, and I am stuck living with him. I have no help and now I am 9 months pregnant. I have no friends or family, he has isolated me completely. I don't know what to do to get out of here and be happy. Any advice?
