Here are my two cents:

Sounded like a classic example of being 'caught out' with canned material. Interesting and revealing that the girl kicked around anyway - this shows that you have qualities that are attractive/appealing to the opposite sex. You might want to check out some of the natural threads on this forum - loads of people seem to think that being natural is the way to go.

I think you should have pushed it a little more at the time, rather than walking out without saying goodbye. In any case you should try to leave on good terms - she is a fellow human being after all.

Also, I'd personally stop trying to knock-off with 4s and 5s mate.
