I'm afraid that once true colors are shown, people don't change back into who they were before. You are seeing his true colors now. He lies, he calls you names, and he has cheated (what I would call cheating). I am very sorry you are in this situation. I wouldn't hold onto the hope that he will suddenly gain an epiphany and be a different person. This is who he truly is. Perhaps he didn't show this to you before. ((((hugs))))))
