I have a question, I don't think I've come across anyone asking anything similar on the board.

This morning my father-in-law asked me if H was mad at him. He said H has been pretty much ignoring him (I think he means not calling, texting, etc.). Now, FIL and I have had a few talks on the whole sitch (I don't give him details, haven't told him about OW). I told FIL that H is ignoring everyone, and that he's pretty much pushed everyone (not just us in the home) away, and has a whole new group of people to hang out with/lean on.

My question... Is typical normal behavior for WH/MLC to get a whole new set of friends/support system, and have almost nothing to do with family/friends?
