I am still here. Your DB pal has got a lot going on, but I want you to know that I try to check in when I can. Sounds like you needed the encouragement.
As far as the answer to your question, keep posting. You are trying to figure out what is best for you and your children - it is not a simple question. Nor is it a simple answer. I will say this though: your W has given you the gift of time if she is willing to live with you for now. That may be a golden opportunity for you.
