Personally... And I don't mean to kick a dead horse so to speak... But if he doesn't trust you... Why move in with him? Is it to prove to him that you're not that type?
I mean... My parents, they fight a lot, and it almost always comes back to the fact that my father is insecure and because he cheated on her he thinks that she's cheating on him because she doesn't think he's attractive or she doesn't love him or whatever dumbass excuse he comes up with.
If he doesn't trust you, I don't know what you'd be able to do to prove your fealty to him. And moving in I don't think would make things better, if anything he might even become hawkish and start really intruding upon your privacy.
And I know that some people say there should be no secrets when you love someone, but well... to be honest, that's bullshit. Everyone needs privacy, everyone needs their alone time and sanctuary. Would you be giving all of that up if you moved in with him?
But to answer your real question, I would talk to your parents, but talk to him first. tell him how it is in your family and tell him that you don't want to do anything to upset them. If anything he should understand and try to help figure out how to make it okay with your parents to help you move in without doing anything (or much) to upset them.
Then if you still feel like it would be okay and something you want to do, talk to your parents. Maybe they would be more comfortable knowing you would have your own room, wouldn't be sharing a bed, blahblah blah... And that could possibly help them adjust.
That sounds like a plan. But I would definetly tell him he has to work on the whole trust thing. Cause I mean without trust, y'all won't be going to far ya know?
But also talk to the Rents and see what they think. They'll be able to help you out I'm sure. Even if it's pointing out some major flaw about why you shouldn't.
Personally, I wouldn't move in anywhere (Unless it were my own house) where I had to pay rent ya know. I live at home now and have a damn sweet deal. No bills but mine, no rent, no utilities. It's great.
But yeah, like Angel said... Watch out for the whole spazzy untrusting thing. Because that won't get better unless you talk about it and do something about it.
