Look, I know it's real shitty. No one wants to be denied the right to go and see their kid sibling. But your parents are freakin' batshit. No offense.

Personally, I feel like you and my son need to go ahead and get married, throw yourself and him at them and yell that you're a woman and they can't change it no matter what. I know they're delusional, but holy shit they can't deny it any longer, especially if you get knocked up.
