Hello, I have 3 SC - 1 at Uni, 2 boys at home with me and my OH who are aged 17 & 15. We live in a house we bought together 4 years ago and we have a DS between us who is 6 years old.
We generally get on well as a blended family and have lived together since 2018 when our DS arrived (initially in my DPs house).
I have recently been finding it very difficult to live with one of my SC who is 17. He is very rude (often doesn't acknowledge you, walks around wearing headphones, if he needs something he doesn't put it into a full sentence etc) and although extremely intelligent and loves school and structure, he hardly talks to either of us and displays many typical autistic symptoms such as preferring time to himself, not communicating (hardly ever says please or thank you) and a dislike of small-talk, strange behaviour (to me) of coming downstairs at 10pm cooking bacon sandwiches a couple of nights a week, having no sense of fear, such as walking to the gym at 9pm on some nights through very dimly lit areas.
I appreciate that we are not on the same wavelength and that's fine, but feel quite awkward around him and he probably does around me potentially, but I'm finding it hard as our values are so different.
Speaking to my DP he tells me to stop going on and just accept him for who he is etc and defends anything he does that might come across as 'rude' but I'm struggling to understand what I can do to make the situation any better.
