Yes! Do not move out despite how hopeless it seems or how much she makes your life miserable. It's your home too and while there's problems in your marriage it took two people to get where you guys are now. Keep this in the back of your mind so you don't sink in self-pity. You appear sincere in your efforts and you are doing right by taking care of your kids. Her anger and mean attitude is motivated by the prospect of greener pastures but don't be discouraged! Do u want to be right or do u want to be married? Leave the OM issue on the back burner for now and cont. w/the 180 but in the most respectful and still loving (tough love) way.
