Name changed for this as it may be outing and don't want my other posts linked.
So ds has no contact with he's dad.
Very long story, but cutting it short he's a drunk, drove him home drunk, left him asleep in a hotel room to go drinking etc so literally not a safe parent.
He got in contact recently via email as this is all he has, he was a changed man etc etc agreed to meet at public place and he turned up steaming and carried on drinking. was really rude, saying he will have ds for sleepovers he will drink around him if he wants etc etc
Ds who is 10 was really sad about he's dads behaviour and said if he contacts you again don't tell me.
Now it's been a few months and ds has just come in to me to say he is playing with a friend on roblox who goes to the same school and she says she has a letter for him from his dad, as his dad is round there for a bbq, turns out her mum is a new gf of a relative of ds dad.
She has said she will bring it into school for him on Monday, he said he replied I don't want any trouble but I don't want it, she said her mum and ds dad have told her she has to give it to him.
Thing is we moved 12 months ago as ds didn't feel safe at our old house sometimes his dad would turn up drunk shouting and stuff, since moving and ds moving school he has been so much more settled. AIBU to go into the school on Monday morning and tell them under no circumstances should letters be passed? I'm not mad at the little girl it's not her fault but surely her mum can see where that is wrong to be getting involved especially since ds has said he doesn't want the letter. If I do go into the school what do I say?
