To cut a very long story short, a friend who I've known for years I had a falling out with, something I don't ever see we can come back from. She went completely off the rails, she is extremely jealous and nasty towards me and it's happened before. Others who are aware of the situation have said I was mad to put up with her bollocks for this long and completely understood why I finally had to just say 'bye bye' to our friendship and her.
Anyway this ex friend is aware of my strained relationship with my in laws, in particular my mil and SIL, it is something I confided in her about. I won't go into details of the strained relationship, but I've put up with a hell of a lot over the years from them both and this ex friend knew all about this. Shortly after the falling out this friend kind of latched herself onto the inlaws over social media, she suddenly started liking and commenting on just about everything they wrote on Facebook (quite literally) and even her kid got in on all this Jazz, who barely even uses Facebook but suddenly began to. It was quite noticeable to myself and partner and also a mutual friend and it was just so blatantly ungenuine. Now this ex friend and in laws have met twice, quite briefly as well, but ended up adding one another on Facebook.
The other day mil,asked me if I had seen this friend, I told her openly what had happened and she is aware this happened before. Mil didn't say much other than 'oh god' and sniggered. The next day this ex friend put a picture up and mil commented on it telling her how lovely she looked. I thought it was a bit much really considering what I had just told her about this person and also that she doesn't really know her. I've also noticed that since this my mil has liked every single thing she has put on Facebook, so has my SIL and her husband. Now I find that a bit strange and I am wondering are they being a little bit fucking snaky toward me? It doesn't really upset me, I just think In my head this is another good and quite valid reason to just completely distance myself from the in laws altogether, but a part of me is thinking aibu?
