D.H.
FWIW - the uninvolved will get that back from the children if it's anything like my ex-ILs. When they were small, ex told me I was not welcome at his parent's house - ok, so be it! Only time the kids ever went there was when ex's sister came in town once a year - she'd come and get them for the day and that's the only time they'd see any of them as she'd stay the holiday weekend w/her parents. Told my kids what I was told about not being welcome (when they were older) and that when they were able to drive, they could go visit if they so chose to do such. With son, it never happened - he has zero connection with most of them tho he'd probably be polite to his aunt. I've wondered what they sometimes think now as they are getting up in years!
(and as an aside - I've stopped by ex-MIL's store w/my dgd - and she barely showed any interest there either - so, just don't do it anymore!)
