There's this girl who flirts with me a lot, touching me, smiling at everything I say to her, the whole 9 yards. Problem is, yesterday she asked me what I do in my spare time. So I told her "go to the movies, read,etc". She then asked me who would I go to the movies with and as a kneejerk reaction, I tell her "with my gf". Then she replies "thanks for telling me, but I asked when was the last time you went?" while laughing.
So basically, I told this girl that I have a girlfriend and I may have messed everything up because she might start distancing herself from me because of that. I have her number, but I wouldn't know what to say to her if I called anyway. Should I continue to flirt with her or just let it go?
