I may not be the person you want to hear from either. However, IMHO, you are showing how desparate you are. You are doing exactly what he asked you "not" to do and you are trying to "fix" things for him as if he was your little boy. Stop trying to be his mother and stop recuing him. He's a big boy and needs to clean up after himself. You are acting all grabby-needy and it is not attractive one bit. He's going to be okay, so find your self-respect and start showing him how classy you are instead of pathetic. You need to detach emotionally & physically. He doesn't want you there when he has OW, and that should be obvious. Don't put yourself in that predicament.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
