Struggling to get my dad to understand my AFRID diagnosis

Honestly my parents were the same way and I found it not worth the energy anymore so I left. I would say to keep setting and maintaining your boundaries as best as you can. Sometimes they never understand and it’s really painful. You’re not alone. Be firm with him and maybe add consequences if you can (he does x then y happens, like you don’t do something with him after he’s pushed a boundary or made a hurtful “joke” so he soon learns that behaviour makes him alone). I wish you the best and sorry I can’t be of more help ❤️
