Hi Tina, I'm sorry to read that your H is a flip flopper. He's very impulsive but isn't that like all the other WAS? I'm getting off topic...
This must be very difficult for you since it makes you question what part did you take in this. When we're so caught up in the sitch we blame ourselves "why did I take him back so easily?"
Let me start off by stating that his indecisive behavior is not your responsibility but setting boundaries is. Take this opportunity to work on yourself and forget about his emotional baggage that he's carrying. He really needs to work on himself or else he might do this again, and again until you get tired.
Work on rebuilding yourself, your self-esteem. Don't let his disfunctional behavior affect you.
Take care of Tina ;-)
