Background so as not to drip feed.
ExH does not communicate directly with me. All communication runs through his GF. They live together and GF has a DD (6).
(We have been separated and divorced a while).
My DC's see their dad (my ExH) once a week overnight.
Youngest DD (6) refused yesterday & said she hates going. I never pressure them - I have found this makes them worse. So she stayed with me.
Today my eldest DD was dropped off early I asked why.
Apparently GF took her DD and my other DD's to a local adventure park. My youngest DD who stayed with me wasn't invited.
AIBU to expect my youngest DD to be invited? I feel she is being punished and is missing out because she didn't want to sleep over and therefore missed the 'fun' planned for today with her sisters.
