Blazin', you said you're just friends and it's platonic, so go for it! If you were going to move in with him as his girlfriend, I'd say, "Hell no!" But, since you're just buds and you will have a third roomie, it sounds like a fresh start just waiting for you. Get out of your rut and try a new city, it'll probably be good for you. I wouldn't get too wrapped up in him, though, just because you will be living together, and if it all goes to shit with you two as a couple, you will be stuck. So, stay friends, but HANDS OFF! lol

Personally, I'd much rather live in NC than Florida.
