you have to focus on YOU and your daughter, push this guy to the back of the line. He throws you crumbs to combat his guilt...It's always all about him, and what he needs to feel good.
this man is not worth your time and energy. I think if you stop taking his texts, calls and remove yourself from hearing about him and his drunken excuses, you will start to feel better. you CAN develop a support network for yourself and there are many people who will treat you with kindness and compassion. what goes around, comes around and it will for him too at some point.
