We have looked after my DH's nephew since he was 12, both his parents are deceased, he was with my MIIL from age 1 - 12. He is 22 now but emotionally a bit immature despite being neurotypical.
Graduated university last year. He is now living with us here (was going to go traveling then get a flat) and behaving really badly. Rude, angers immediately if challenged on anything, bit aggressive, shouting, swearing. He is much bigger and taller than me now. There are months ahead of us now his travel plans are cancelled.
Over the last week or so we have had big rows because he almost certainly (obviously no test) has corona wtih very mild symptoms. Went to the gym all week, didn't distance or wash hands, just selfish and petulant (well you've already got it so no point, stop treating me like a second class citizen, fucking shut up etc. ).
I was obviously angry with him although not shouting. I said if he can't behave sensibly and consider others, then he can go and stay in his GMs house as she is away. It is in another city. Now he is holed up in his room, not answering messages from GM, coming out after we've gone to bed and raiding the fridge.
I feel so uncomfortable that he is hiding and obviously I know that I have to get him out and talk to him. But what can I say?
I need to think through a plan.
Sorry this is long, but also, such a very short version of the situation!
