A dear friend is having terrible problems with her eldest boy. He's heavily into drugs, and has been stealing from her and local businesses to fund his habit. She's had to buy a safe and lock her purse/cards/phone/tablet etc away all the time. He's also been violent with her when she has refused to give him money.
Me and a couple of other close friends have done our best to support her through this but none of us want him anywhere near our children or our homes as he can't be trusted.
Next weekend we're having a get together and I want to invite her, her DH and her younger boy, but want to make it clear that the eldest is not welcome. My DH thinks this will cause an upset and says we should just lock our stuff away whilst he is here, but that would be very difficult if other friend's kids bring their tablets/phones/money.
He probably won't even want to come but I want to spell it out beforehand just in case he turns up.
What do you all think? Am I being unsupportive? I'm sure if it was one of mine I would understand the reasons mine were being excluded.
