Met an HB7 at a club a few weeks ago. Didn't make out w/ her that night, but most likely could've. Within the next few days, she text and called often and after two weeks of phone & email conversations, we're finally going out this weekend (she invited me and she made it clear she'll pay for dinner & movie

). The problem is that it seems like she's getting too attached and I really don't want a relationship. Would like to mess around with her, so how can I get her to agree to just do that with no string attached, without looking like an ass hole?
