So I've been talking to this girl for just a few days and we go out on a date and apparently some other guy who's interested in her saw a photo of us out and got super upset. Anyway, she tells me she has no interest in this guy and blah blah blah she just feels bad for him and proceeds to lightly compliment me on a lot of my physical attributes along with social tendencies. e.g. "You're so funny!" and "I wish all guys dressed like you." So after texting and talking a bit over the next couple days, I find out she went over to the house of the guy she told me she "had no interest in." Should I drop her on the spot, as that is my first instinct, or if not, what should I do?
