NC as per subject title...
My dd and her dp split a couple of years ago, they have dc. Things are tense between them. We remain cordial and friendly with son in law (SIL), but not close.
dd has shared some things about SIL, but I recognise this is one side of a relationship.
I'm facebook friends with SIL, have been for many years. When he posts phots of him and my dgc I 'like' them. I ignore any other posts, don't comment.
Now SIL has a new partner. I know from his fb that they are on holiday together. I don't think dd knows this. I would never tell her.
But... do I disengage from SIL's fb, and how? I think I should. But if I just 'unfriend' him will he think it's because of the new gf and the photos (I'm not really overly bothered that he's in a new relationship). Should I discuss it with him? Am I overthinking it?
