I am my wife's second marriage and so far I haven't had anything to do with her ex, but that is about to change because we are taking over custody of their son. I know what this guy put my wife through when they were married and I don't know how I'm going to deal with him without losing it. I know I have to, but it's going to take an incredible amount of self control on my part. Does anyone here have to deal with your wife's ex husband?
