Cooked tea and watched the end of a movie with DH and DS(16).
DH said to DS "how about you make us all a cup of tea while mum & I load the dishwasher?"
DS doesn't move and says, "nah, I'm alright, thanks." DH asked him again, but somehow this then escalated into a huge row with me in tears saying he's an obnoxious, entitled brat, DH going on about how he needs to learn to be grateful/show some respect and DS storming off outside for 20 mins (could see on snapmaps that he'd gone to sit on a bench down near the main road, about 10 mins from us).
He's now back in, went straight to his room, but took his gym bag from the hall with him. DH is worried he's packing a bag and is going to leave once we've gone to bed ...
Don't know what to do now, but don't want to leave it overnight. I genuinely don't think we were in the wrong (although shouting is never good, I admit) but I have been doing so much for him over the last couple of months and he just seems to take everything for granted.
