<human>: Can you provide a brief overview of the text?

I met this girl at a new years party at my house. She's very nice and smart. We talked the whole night. We went on a date that weekend that ended in sex(she suggested). And a second date this passed friday. She stayed at my house and we were together most of Saturday. She asked a lot of questions and sounded like she wanted something serious with longevity.  She put the relationship up on Facebook and for some reason that made me uncomfortable. I called her and told her I don't think we're looking for the same thing and she says I was just trying to have sex and leave. Am I an asshole?
<bot>: we have 2 dates,both end in sex. I decide I'm not interested. She accuses me of using her for sex.
