Of course she is fine being separated and apart. As I said she has a darn good gig! She has you eagerly waiting in the background ready to jump when she needs you but she knows you will stay out of her hair when she tells you to. She only has to deal with her kids 50% of the time and when she wants more than 50% she gets it. And she gets to be single and have other men and her freedom. So yeah, my guess is she is quite pleased with the setup she has created.
We suggested you "go dark" aside from the children so you can work on you. Nobody is telling you to "stay out of contact". We are telling you the contact you have is not conducive to a reconciliation.
Why would she WANT to be "pulled back in" full time when she has you part time now and the single life?
