Congratulations doodles! Im so happy for you! I think that this is going to be a great thing for you.
As far as the new guy goes, I would imagine that hes probably really confused. Ill bet that he didnt DB! So maybe he hasnt quite come to terms as well as you have with your sitch. Is his wife as much of a weasel? It seems like when our spouses act like such terrible people its a little easier to kick them to the curb. Put your DB priniples to work here if you want, they will work in many other situations. But maybe you dont need his baggage, especially with all you have to worry about!
Vicky, I felt the same way! I met some uber-losers while I was dating, I got so angry at my H for putting me in that position.
I guess I gave the wrong finger to the wrong man...
