I just got the rage on your behalf reading that OP.
So basically - you had to ask him to “help” (to look after his OWN CHILD ffs!) so he punished you by:
Taking it upon himself to disinvite you from the planned night out
Tell you he needs to be with people who “build him up” ie. not people like you, who ask him to you know, be an adult and look after his own child. Total manipulation.
Deliberately stayed out all night and probably loved the fact you will have been worrying about him
Stays in bed again the next day despite knowing you have a doctors appointment for your LO
Gaslights and victim blames you for being upset about his absolutely disgusting and selfish behaviour
All thus in 24hours? I’d be interested to know what other abuse he subjects you to and blames on his ADHD?
He is a childish, peevish, manipulative piece of shit and I hope you have the strength to not let him come home.
C’mon OP - you know this isn’t right and won’t get any better.
