DS has been friends with another boy at school for a couple of years (they're in primary school). It's a bit of a toxic friendship and I'm not very keen on this boy as he has behaviour issues & made a racist comment to another child last year. I've been careful not to let DS know that I don't like this boy as I feel that it should be up to DS to make up his own mind about him & I don't feel I should dictate his friendships.
DS has started pulling away from this boy as he says that he's mean and he's starting to recognise that he's not a particularly good friend to have. This has now cumulated in them having a bit of a falling out and DS doesn't want to be friends with him anymore. However, we had already said that DS would go to his birthday party.
DS is not massively keen to go although would quite like to do the activity because it's fun (not because of seeing this boy). I'm not keen on him going as I don't want DS to be sucked back in to being friends with him again. WIBU to message the mum & say DS can no longer make it?
