Family issues

C – my brother in-law said to me that I should not get involved in my father in law’s birthday planning because he’s his father, not mine. I sent him a text asking him why he is alienating me and and he refused to reply any of my text messages. Instead he tells my husband to warn me not to get involved.
T – he’s undermining me, I feel invisible
F – angry and sad
A – I leave all the family WhatsApp group and I tell my husband that I won’t be attending any future family gatherings where this brother in law is.
R – I’m not sure what the result is.

My question – I’m finding it really hard to think intentional thoughts about this circumstance. I’m trying to think about it differently but my brain isn’t coming up with anything different. Please help.

Also could my result be the same as my action?
