Snowy, he is lucky you didn't go psycho on him and bust all the windows out of his car (Note: I am NOT advocating this, but it seems like a fun fantasy)
Seriously. He's such a trollop.
I'm not surprising his spinning now. He has neve rknown WTF he has wanted. release yourself from this man. You deserve better. he can't even follow one train of thought. Geez--you moved out an dnot a week later he's "single" all over the internets and having the nasty OW over at your marital home. What a turd.
Let them have eachother. It truly is the best revenge.
His conscience will catch up with him eventually. Not now because he's still vacillating and hasn't felt fully waht he's done and is busying up free time with teh skank married other woman/babymomma. But eventually, the weight and gravity of what he has done WILL come down on him hard. It will suck for him. A guilty conscience is a motherf-cker.
