How do I know if I'm just getting a pity date?

Anonymous
I asked out a friend (or at least someone I've known a couple years) and from her behavior afterward and during and after the date, I just got the vibe that she was just saying OK to one because I know her and she didn't want to reject me outright. And, despite the signs she gave me, she wasn't interested in the first place, which affected how the date went because that "vibe" wasn't there. Like she was just obligated to spend time because I asked.

Should I trust my instincts on this one? Some people say... "oh, she's just waiting for you to ask her on a second one"..."oh, she's just waiting for you to be more confident and sweep her off her feet", but trust me, if someone doesn't want to be swept of her feet by you, it's hard.
