alright... are you talking about the kind of clingy where they are always holding you close or the kind where she won't let you hang out with your friends?

If she's the clingy that keeps u from ur friends, "fuck" her (not literally, unless u want) leav her ass and never look back.

If she's the clingy that's all over you, keep her, cuz those ones are awesome in the sack.

Personally, i like it when girls hold on to me. i like to be close to my gf.
