loll be cautious though, sometimes tomboys are tomboys-- but they are still girls. SOMETIMES, they will turn somewhat more girly when you do end up being together... will you then dump her when you find out that she's also clingy? lol... talk it out with your girlfriend... let her know you're serious about this; and if she does not listen to you; well that's just too bad--- break up with your girlfriend because of your girlfriend.. not because of another girl!!! Deal with one relationship at a time! in my POV i think asking a girl out behind your girlfriend's back is cheating.
