Good point. That is why counseling is so important. But both partners have to want it bad enough to go. He is in a MLC fog right now and doesnt see the point. Like I said, hopefully, the thought of losing you and the "family" will be enough motivation. You have to follow through though and stick to your guns. I would say a minimum of 6 months seperation from him to really feel the lose. Tell him to leave and live his sick and selfish life... you have too much self-respect to be someones object YOU WANT A PARTNER. If he threatens the D again. Just tell him that "You do what you need to do and I will do the same... and let him do the legal work if he feels necessary. Chances are it will all be a bluff though. I would seek legal counsel to learn your rights and legal position. You dont need to let him know that though.
You both need time to set away and find some clarity.
A clean slate is possible if both partners are willing. I pray that he can "man up" for his family. Putting the pride aside and getting help is not easy. We all can relate. He just needs to have his priorities adjusted. I wish he had a brother that could kick the crap out of him and put things into perspective for him. I know I would. He has no idea how good he has it until it gone. "They think they know, but have no idea..."
Show him by your actions not your words on how much self-respect you have... Whether it's today or Sept. it's NOW all about Bunny and her happiness.
