I found out that ex-BIL is staying with my friend and her DH tonight while he is down to visit his DC. I do not see ex-BIL socially. His breakup with my sis wasn't pretty.
I never asked them to cut ties with him after he became my ex-BIL, even though they only became friends with him through me and I'm not suggesting that they should not continue to have a friendship. It's totally up to them of course.
But... I am (I thought) close enough to this particular friend that it feels weird for her not to have even mentioned it. Just in an "FYI" kind of way. It feels a bit like she's hiding it from me. It's a really odd feeling.
I don't know if this is an AIBU really. I guess I just wanted some opinions.
