Adult son is three years in to good relationship with nice woman. He's moved 300 miles away to her home town. He doesn't contact us (self, husband, other siblings) and only visits under sufferance, although I can sometimes catch him for a chat via Whatsapp and he's lovely when I do, even if he has to go quickly to do stuff. It seems like he would like to forget we ever existed. I don't think he had a bad upbringing and when he lived with us we got on really well. He's undiagnosed but probably on the spectrum. I'm worried that if I raise this as an issue it will just push him away. I don't think he means to be hurtful but sometimes he really is - for example I asked if we could chat on mother's day and he said no because he was going out with his partner's family. I hear about adult children 'going no contact' these days, something I definitely want to avoid. Should I just accept that it's great he's happy and doesn't need his mum anymore?
