Oh Peggy. I don't mean this as a flame AT ALL because I know how hard it is - but how many times are you going to let this happen? I think you hit the nail on the head the other night when you said something along the lines of "I'm not going to let him treat our daughter this way" or see him treat you this way or whatever. It's true - your daughter - and YOU - deserve to be a part of a loving and supportive family.
Sort of have to agree here. You cant live your life on pins that he might decide today he is going to leave or treat you like garbage. I dont know how you can get him to make that promise and believe him, but he definitely needs to do some work to regain your trust/loyalty, etc.
