FYI, we went on a date, then said she wanted another one, then told me she had a boyfriend (which was a lie because I came across her on tinder just now)...

I really am never gonna see her again, unless I bump into her, which I would just ignore her. I doubt she'll tell me the real reason, but is it worth a shot? Yes, I know its desperate, but I'm not trying to get with her anymore, its just for advice.
