I am so sad about this!?

I feel really bad for you. I cannot imagine the hell you are going through. The man is a pig, thank god you didn't marry him and have children with him. Do not think that he will treat the new girl any better than he treated you. Did you work and contribute to that house? Is your name on it? See a lawyer about getting your share of the house then see a therapist so that you can move on with your life. I know you won't see it this wqay right now but you really are lucky that he pulled this now rather than later. Good luck.
