How to ask the girl to "just be friends" for future potential...

About me for a second: I'm dating/looking for a relationship at this point in time.

So I asked this girl her number at a local book shop while we were studying with a nice "Hey... i'm about to leave but i just had to stop and say that i think you're really cute... would i be able to get your number to go out to coffee sometime?"
We went to coffee and it went really well. We definitely have chemistry but i'm not sure how much of it is sexual at this point. I don't doubt that it could form but she seems really hesitant about anything i do in that arena.

Meanwhile... I think she's a pretty cool girl. We have a lot in common and we're both graduating college in May so it's not like we're going to be around each other that long anyways. I was thinking about getting coffee sometime soon and bringing up the idea of "being friends" because that seems like the best case scenario for us. We'll either 1.) end up being good friends because we have alot in common. or 2.) start as friends and get to know each other a little better and maybe date a little bit.

So my questions: How do you think she's looking at it at this point? Is she thinking I'm trying to date her, was she just "getting coffee" to meet someone and its assumed friends until proven otherwise?

And then how would you go about bringing that subject up? A simple question of "So what do you think about us being friends?" that sounds lame... but yeah.
You're help's appreciated guys!!

I think that in her mind she is thinking you as a possible mate. BUT she well not really FEEL nothing untill you give her a reason to. By showing you worthwhile guy.
Take her out to somewhere more social place, like club and have fun with here then maybe end up to your place or her place and after whatever happens dont give her too much, give little then step back little. This will get you a sexual feedback. Works for me everytime. This is what I would do.

Just be friends with her. Just hang out, be interesting and loads of fun.

Don't think aboutthe future so much since well, you just met her. And you don't know enough about her yet to be thinking about the future and her place in it.

Next time you hang out, ask her what her plans are after graduation, but not in the context of whether you would be part of it. Just be interested in her too. With luck, you'd have a better idea of her plans, but more importantly, you'd have a better grasp of whether she's worth knowing at all.
