Honest opinions, I think I can take it (Eek) Bit of a long story. I have an issue with my father's favouritism towards his daughter from 2nd marriage. It kind of flares up every now and then and fortnight ago was one of those when I wanted to take my DSs to visit him a few days before 75th birthday party and he said no, the weekend before the party he and wife would be much too busy to have us in the house - DSs are 12 & 13 so not babies that might be hard work - they'd spend all day in the pool anyway. and plus, the party was in a hotel, fully catered and mid-week so what did my dad have to do in all honestly. I wrote him an email saying that I bet if step-sister had kids, they would have been welcome (there is a long history behind this) but yes, it was a childish comment cos I felt hurt that he didn't want to see us. BTW my dad lives abroad, so it fitted in with half-term.
Instead of a reply from my father, his wife sent me a long vitriolic email saying basically that i am a sick and twisted person who hides behind a mask of niceness and that I need professional help. AIBU to think that a private email between a father and daughter is none of her business and she was out of order. If that was there shared opinion, fine, but response should have come from my father, surely.
