She has been divorced from BIL for 3 years but is godmother to my niece, so shows up at parties and get togethers because my SIL (BIL's sister and mum to my niece) has stayed quite friendly with her, I assume for niece's sake. My BIL has met a new woman who is just getting to know the family at the moment and last night there was a family get together for niece's birthday. Ex SIL showed up, showered niece with gifts and did the whole small talk thing before leaving after about an hour or so. I don't have a problem with her really but certain members of the family really dislike her, my MIL included. SO, the usual happens last night, after she left she became the main topic of conversation, which is getting pretty bloody boring after 3 years, lots of whispers of 'what's she doing here' blah blah blah, MIL going in a huff with SIL for inviting her and BIL getting pissed and angry. It really wound me up last night because I thought it was a bit unfair on BIL's new girlfriend. So AIBU in wishing she would just make time for her god daughter on their own terms outwith the immediate family as every time she shows up it creates tension? It's getting really annoying.
