It takes two to tango - you're upset that he didn't marry you and has ended
the relationship and threw you out of the house.
You're just as well to blame: Why do you move into his house without
having any protection of a rental agreement or some back-up living situation?
If you expected to get married why did you not discuss this with him when
the time was appropriate? If he said no then, this would have been your indication to leave. He was awful to you? Why did you let this happen?
You're playing the victim here who is out for revenge! Trust me, you'll
not get the satisfaction you seek in doing so.
