The fact of the matter is the first time he cheated on you you should have been gone. I am sorry, but a man who cheats on a woman is a coward and a user with no respect for her. He may say he loves you, but cheating goes against the very definition of what love is about, and actions always speak louder than words. Leave him to deal with his own consequences, and don't budge when he comes crawling back, because chances are he will, saying he loves you and he knows he made a mistake. Don't give into his game, because he is just toying with you. Move on and don't look back.
