Hi, this might get a bit long so I apologise in advance.
Basically, mum and brother don't speak due to mum not making an effort with brother and nephew. Brother got fed up of this and mum and brother's gf/brother had many cross words over it and don't speak now.
For Christmas, I asked brother in November whether I could buy a certain item I knew nephew would like. All agreed I'd be buying that and brother even said MIL couldn't get it as I was. Our mum has now bought the present that I was buying for nephew. I told her I was getting it and she didn't really respond. Just said I could get the bits to go with it instead. Then said brother wouldn't accept gift anyway.
When I asked what else I could get nephew, brother said nothing as nephew has everything and I should get the present as that's what we agreed on. He said he won't be accepting gifts from mum or sister (who also hasn't been to see them for the best part of a year) this year anyway so it doesn't matter.
I don't know what to do. Yet again I'm in the middle of something I don't want to be. I want to get the present as I obviously came up with it and asked a while ago but fear mum's reaction. She tends to take these things very personally and will see this as me siding with brother. Coupled with the fact that she hasn't been bothering with me either for the last two months (all contact initiated by me).
Any advice? I want to get the present anyway and just be done with it but not sure how she will react (IF she finds out, considering she doesn't go to their house/speak to them and has no way of getting their presents to them without doing this).
