I wish there was a formula I could give you, Sabrina, to make your H stop cheating. You are doing the right things with the 180. Keep doing that and also GAL. But ultimately, you can't make your H stop cheating on you. He has to decide for himself. You can do all that you can to make yourself more appealing to him and to make yourself feel better about yourself.
Keep posting! Many people here can give much better advice than I ever could.
