Do you drink heavily and do you have a problem with alcohol? Just curious why he would accuse you of being like his alcoholic mother?

Either way, he's the one who cheated, so he is at fault. This man sounds very manipulative and like HE'S the one who cannot be trusted. One can never trust a cheater. And once a cheater, typically always a cheater.

Very sorry for your pain. He's not worthy of you, though. You can do far better and find someone who is honest, decent, trustworthy and honorable. Not this shmuck.
