Name change.
So BIL's girlfriend has been doing some very dodgy behaviour towards me for a while, trying to exclude me from DH's family and so on. All very under the radar stuff and nobody quite believed me as it could all be easily explained away.
However, recently DH's aunt also joined in very publicly (by accident) and very obviously against me and very obviously part of a discussion about me with BIL's girlfriend. DH's entire family saw this. It was very hurtful and she later tried to explain as some people just don't get on and she was going to continue saying such things and I would have to put up with it because we're family. A lot of the family have said to me or DH that it was completely out of line. I said its best we don't associate with each other anymore. Told MIL that I didn't want either of the 2 involved seeing DD again as comments were concerning a condition that DD might have and they are both quite open and bitchy in person.
The issue here is, the rest of the family seem entirely not bothered by their actions and it is now me being left out of things. BIL's girlfriend has sent pictures of them all hanging out together today. Originally was supposed to be her, MIL and me but I dropped out after those events and they decided to invite DH's aunt instead. I 100% think that this was rubbing it in my face and coupled with other actions seems like BIL's girlfriend is pissing to mark her territory with MIL.
I don't want to get into some silly fight but obviously I still like my MIL (although am a bit disappointed that she didn't stop BIL's gf from sending pictures for me to see). I honestly thought I was getting along with BIL's gf and DH's aunt and the comments came out of nowhere. So I don't really know whether I should just leave the rest of the family to it and say well clearly they're not worth my time and be silently a bit upset that MIL won't stick up for me. Other option is stand up to both of them but I don't really see if that would do me any favours as they're very tight and very good at explaining away their actions.
