there was a book recommended by my C, "families apart". It is out of print now and I got it from Amazon. This is the only book on co-parenting that I read so I am not sure how good it is. May be you can check it out from the library. I gave it to another friend who is D'ing, or I could have sent it to you.
I do believe a two parent household is best for the kids. But in your situation, at least the current moment with the friends that your H is hanging around with, may be just you as a single parent is best. Just my opinion. I think what would be missing would be a good father figure and you will have to find a sub for that. When I was considering D, I thought about who would be that father figure, I have my brother and other relatives in mind so I know my kids will be OK. That's the same time I realize how much more my kids are around the motherly figure than male figure. My H is spending tons more time with the kids now so that's good. But the kids still ask for me when I am gone, but not daddy. They are used to him just disappearing at times. Sad.
