My mum is one of 5 siblings who have a chequered history of in fighting and bitching behind each others backs. I haven't kept up with any of them over the past few years as the emotional energy required is exhausting- even though I do miss my cousins who I was once close too.
Last weekend one of my cousins got married, my mum found out (through the dreaded social media) that she was the only one of the 5 siblings not invited and has seen pictures of the other 4 all celebrating and talking about what a "great family" they have.
My poor mum is in bits, she hasn't fallen out with any of her siblings (as far as she knows but they have got form for randomly cutting people out) and I am so angry with the way they've treated her it's tempting to comment on FB and ask if my mums invite got lost in the post
They're a pretty toxic bunch so I don't think mum is missing out by not being in their lives but obviously she doesn't see it that way. Any ideas how I can support her and build her up following this?
