Changes of environment (like moving) are known to trigger changes in behaviour that were latent. It may well have been this change in behaviour (acting more confident, more mature maybe?) not the change of locale. When I say latent, it means that you felt more confident for a while before the move already, but it took the move, which brought anonymity, for you to externalize it. This is why tourists act crazy, and even introverted shy people can act exuberantly on holiday. Or like your case, after a move.
