1. Sounds like you are doing pretty well given the circumstances. If it's really over with the EA, then she must be suffering withdrawal, so no surprise re the spewing, lack of physical contact, and space. Good that you're not accepting the spewing; sounds like you are pretty calm/detached.
2. Yes, my W spends money the same way yours does. That is one of the things I am looking forward to in terms of separation and divorce...separate bank accounts!
3. Re kids. Yes, it's best to shield them from all of this stuff and that they don't take sides. So sweet that he came and told you that you were his dad, no matter what. It takes a mature and brave kid to say that.
4. I think my W and I have done pretty well in shielding our kids, except for the few flare ups when my W was so loud, the neighbors next door could hear. I know the kids heard her shouting and screaming but they've never mentioned anything about it to me.
5. Good luck finding a counselor. Take your time to find one you really trust or else you won't be able to open yourself up the way you need to. I tried out a few before I found the right one.
