Sounds like you need a compromise.Try this one on: she gets to go to clubs on her own if she likes. Restricting that sort of thing from a partner just isn't fair: if you have trust issues, work on'em, but effectively grounding her like a parent isn't salient.
AND: you get to go with her now and then, too, if YOU like going out clubbing, not because you want to police her. If where she's going you're underage, then ask for a club night now and then with her somewhere you CAN both go.
