So ive been apart of a mum group since my DC was 4, they are now 9. We as a group used to get on well and have get togethers at each others and I generally liked everyone.
I was always wary of 1 mum though. She is the one who invited me into the group and seemed to have set it up back then. I'd have said we were friends but not extremely close.
Anyway this group seems to have drifted since a couple in the group split and this women who set it up left the group chat for no reason at all. I asked if all was OK and she said she just needed to reset. She has been known to have random emotional outbursts and hibernate away. When she left our group chat she also removed me and a couple others from another group chat and distanced herself from everyone. We all had a get together at Xmas with the kids and although a bit awkward it was ok.
My ex isnt nice and has been awful to me which the group knows and this woman knows because shes asked me questions. I found out last week that she had asked my ex round her house to carry out some work. She could have asked so many other people its not niche. But she chose him. Even though shes all about "girl power" and friends looking out for each other.
She doesnt know i know but im just so angry at her. She also is messaging him being quite friendly with him (not in a romantic way).
Aibu to be angry, how do I approach it. Do I say nothing? I just think she is so two faced! She text me the other day wishing my child well after finding out he was ill from my ex.
I still have another 18 months until DC moves to high school.
