Dude, sorry about your parents. I see 3 options here...go no contact, assert boundaries that condition contact on their behavior, or do nothing and let them keep acting like this. There may be other options I don't see, but it's important to recognize they're probably going to act like this for the rest of your life, so it'll be best to be intentional about how you interact with them. They sound like the kind of people who'd try to interfere/fuck up your relationships if they don't like who you're with, and it sounds like they're going to be really good at finding fault. A therapist could help you unpack all their bullshit and figure out how best to communicate with them
