DS is 18.
Every time I tell him something isn't acceptable or give advice he is aggressive verbally.
For example - today I was helping my mum. DS was at home with his dad. I asked how he was feeling because DS has got a chest infection and said please stop vaping, as it's bad for lung health. I was sent a 90 second voice message rant about how there is something wrong with me and I should not go on about him vaping.
A few days ago , he blocked the toilet again by using a whole roll of paper and not flushing between wiping. I asked him politely to flush it several times and again he started shouting.
He has ADHD but this is just making me feel like he's totally unapproachable.
He gaslights me by saying oh there's something wrong with you/ you must be mad etc. He was behaving antisocially just before Christmas, riding on back of a moped that he knew was stolen. No helmet and the rider had no bike test or insurance .
I saw him and told him but he lied and said "It wasn't me!". There is a lot of lying happening
