Yes, I found out I am rarely mentioned at all (H says he avoids the topic). In the mess of all this, H got a new job so it was a perfect time to 'clean slate' it with people. He doesn't mention a word about being married, and they probably have no clue I exist. Wow, sounds like our spouses are very similar.
Right now, H wants everything having to do with a single life, and still have the kids on the side.... Sad, so sad. He is (like your W I am sure) missing out on so much. I feel like the lucky one, privledged to be around my kids a lot. They are fools.
