Can't really judge your situation on the little information you've given us, it takes quite a bit more than that to be able to give any valid advice...

First of all, how old are you? Would the move be an upgrade from where you're at now, purely judging from the kind of place/neighbourhood/city you'd be living at? Do you honestly think/believe your band will be succesful, or is that wishful thinking? Do you have a job that you love and/or has a promising future?

Friends come and go, but your TRUE friends you will never lose, no matter where you are on this globe...
