Dear Zahara:
I don’t see any way to fix a relationship with a man who told you that you “are only a woman he bought online to be his slave”.
I think you need to contact a women right group, a group that advocates for women in your position. There are also shelters for abused women who leave their live in boyfriends or husbands. You met him online, can you go online in search of such groups and shelters, counseling and any practical help possible for yourself?
