Ex H and I co-parent - normally reasonably successfully, in spite of the fact he has always been a bit anxious. However, over the past year I've noticed he's started behaving like an exaggerated version of himself. Without too many details as I don't want to be outed - he thought one of our son's had cancer (because he thought he had overheard a nurse saying it when he was admitted to hospital with something really straight forward). Since then it has sort of spiralled - everything that happens, he is out of his mind worried and he's convinced himself that there's something more sinister going on and DCs need to go to a specialist. I really lost it with him and told him I wasn't prepared to go along with the bullshit anymore.
Anyway, this week the boys are with their dad. It seems to be fine - the kids were happy to go on Sunday. However, usually he's quite chatty with me during the week and we talk about the kid's stuff and I have the odd message from the kids. I haven't heard anything since the argument. Wondering if anyone else would be worried? He'd never do anything physical to hurt the children but I'm really worried about the emotional impact he's having on them.
