Ds1 is 10 and ds2 is 8.
There is a sports final in London next week and ds1 is massively into the sport and his team is in the final. Ds2 does not follow this sport at all but found out last summer that unless he attended the games he would see a lot less of his dad over the summer than ds1
.
Anyway, until today I had assumed that ex would be taking them to the final, but it turns out he has a gig (pathetic wannabe musician at the age of 48) so the dc will be making the 3 hour journey to London with ex's df and dsis. Df is 84 and quite restricted in his mobility, though otherwise fine. Dsis has a mobility related condition and uses a mobility scooter. She also suffers from fatigue. They are both mad about this particular sport and will want to concentrate on it - ds2 isn't and won't. He's only going to be with his dad, who now won't be there.
AIBU to not be happy with these arrangements and want to intervene? I have taken ds2 to matches and he needs a fair bit of entertainment. Neither of these people will want to provide that, and though they are very lovely I know it will be a difficult day for all and ds2 would be better off with me. I even have doubts about ds1 being just with them, but am telling myself that's silly. Ds2 has no reason to be there and I want to say no.
AIBU?
