Perhaps this belongs here and not AIBU...
DS2 (9) goes to a dance and drama club 10.30 - 2pm on a Saturday. He's always had a love/hate relationship with it and moans regularly about going but does enjoy it and loves being in the termly shows they put on in a local theatre. He used to do just the dance bit in the afternoon, but as the rest of the group did the drama too he was a bit left out so he started that too; the teacher reported he was a lot more lively and involved since doing both.
As the dc have every other weekend with their dad it's always been a sore point. He lives locally so no bother to take him, but as ex often has gigs on a weekend he'll often take them to his mum's in another city, causing ds2 to miss the class. I think this has exacerbated his reluctance to go as he gets behind in things they are rehearsing and it's not such a solid routine. Both dc hate going to the other city and have told me and ex this many time. DS2 has told me he hates missing the class but I think he hates going because he gets more screen time when ex stays at home and he (ds2) knows I'll be more receptive to his complaints if he claims to not want to miss the class. I've offered to have the dc when ex has a gig (we used to do that anyway ) but he wants to deprive me of more time with them so takes them to his mum's despite them not wanting to go.
Today they are at ex's but his car has broken down so I was going to take ds2 to class and drop him off after. He flat-out refused to go and it developed into an argument, which I'm ashamed of. I said some nasty things about ex, which I so regret - we split 4.5 years ago following his infidelity and I've never been remotely critical of him, despite having so much ammunition over the years and the dc themselves moaning about him to me, and now I've blown it. Just stuff about him being lazy (he is) and ds2 being welcome to sit on a screen there for the entire weekend if that's what he wants (there's no gig this week) etc. Ds2 was crying and now I've dropped them off, so no chance to talk until tomorrow evening so I feel horrible.
I really want him to do the class - he's shy and it has brought him out of himself. Plus, and this is the reason I brought ex into it, he is obsessed with bloody Roblox and YouTube vidoes, and I know without the class the whole of Saturday will be a constant struggle to get him off. It's so hard to set up routines, because eow they go to ex's and do fuck all except sit on screens. I do blame ex for the whole thing as I feel if he had been more on board with it ds2 wouldn't be refusing to go. I honestly think he refused this morning because he knew at dad's he'd be straight on screen, and didn't want to miss out. I didn't let him on this morning and he has no ability to wait for things he wants.
I know I was UR to say what I said and upset ds, but AIUR to want him to go to the class? I think we'll have to leave it now for this term as he's missed so much, but would you try again after Christmas?
