Does she want a relationship or just a friendship with benefits

I met a girl online back in April and we had a one-night stand on the night we met. Then a month later we went to the movies but we didn't get past first base that night. Between those two times we texted each other every day. After the movie date I concluded she was not relationship material, but still friend material. Then we started texting every couple weeks instead of every day. And now just recently in the past week days, she's been texting me every day. She's gonna be transferring to the same school as me and will move into an apartment just 2 blocks away from mine at the end of this month. She's a really sweet girl. She has mentioned several times (even a couple days ago) that she hasn't met any guy as sweet as me. The truth is, and I know this may sound harsh, but I'm much more interested in the sex than anything else even though we did it just once. I have absolutely no interest in being her boyfriend. Movie dates, partying, and sex are the only things I'm interested in doing with her. And she has told me once during the summer that we will definitely party together once school starts. She hasn't hinted to me anything about getting into a relationship. Who knows. Maybe the comment about me being so sweet was a hint. It's not like she texts me all the time asking when will we see each other again. We both worked different hours this summer and there was no way we could meet up in the past 3 months because of that. But now that school is approaching, we will be moving into our off-campus apartments and we told each other several times over the summer that we will definitely hang out once school starts. So what do you think she wants?
