So BM called the step kids tonight (we have them for hols) and told DSD (10) she has an opportunity to meet a famous type person. DSS(7) and my DD(9) are not invited. This is on a night she is at our place. BM didn't mention this to DH before telling DSD and has put him in a position where he has to say yes. I had plans for us all that night (just movies, but there isn't another time we can all go) that now can go ahead. DD is jealous as hell that DSD can go meet this person. DSS seems a bit put out too.
I'm really annoyed. I'm happy DSD gets a cool opportunity, but sad the others miss out. I'm annoyed it's ended our family outing plans. I'm super p1ssed BM did not discuss this with DH prior to telling DSD.
Am I being unreasonable?
