Get a DB Coach. I highly recommend it.

Also check out the program by Dr Ellen at http://www.lightherfire.com (there's one for men and one for women) I think this program works best if you are somehow living together in the same house. I am sure if your W listens to the program (for women) she will think twice. It should also work somewhat if you see each other once in a while. Otherwise it will improve how you relate to women in general and improve any potential future relationship.
Personally I do not recommend coaching through Dr Ellen I think because she didn't tell me what I wanted to hear but you can email her for some free advice if you like.

I too am going through a separation and a possible divorce. But nothing ever comes close to the person we married to begin with. This much I am sure.
So any help would be most appreciated. Link below:
