My boyfriend came and asked me to move in with him.I gave him my whole tax kick to cover 8 months of rent.Ever since I gave him the money he's been starting fights with me and at one time asked me to leave.I've only been their a month and he's denying I gave him the money.I was stupid and did not get anything in writing that I gave him the money and for what purpose.Except for a with drawl of the amount from the bank.Is there any way I can sue him for my money back so that I can move out.
