<human>: Can you provide a brief rundown of the text in within 3 sentences?

There is a girl in one of my classes that i always flirt with, and we have some good conversations. We have met once out of class to do a project and have texted a little bit also. I decided to not be too forward, and I simply asked her if she wanted to "grab some coffee" today after class. Then things got a little weird. She was totally awkward and blushing and was like "umm I don't know.." I figured she just didn't want to, so I responded "hey, it's fine, you don't have to say yes." And then she started stammering incomplete sentences without giving me a chance to respond going "I don't know, what's the context, I mean as long as its not Bartlett coffee (we had just had a conversation about how much Bartlett coffee sucks), I mean I don't have too many... I'm sorry I'm so awkward... Um.., but I kinda have a... I... As long as... Well I have to go to lab, talk to you later" and jut kinda scurried off without giving an answer. Most of this little bits are word for word to my best recollection. Hard to interpret it all, but for "I kinda have a..." It seemed like boyfriend would be the next word, but she changed sentences too fast. Now, I'm no fool, and I realize this is more or less a rejection, even though she never said no. Even if its not, she probably wants it to be platonic. My two questions are what do you think this little freak out was all about when we talk so easily and I was totally not awkward, and also, how should I deal with this when i see her next on Friday? Should I pretend it never happened? Jokingly tease her? Ask what was up? The whole thing was kinda bizarre , but we are going to be sitting next to each other for the next three weeks at least, so I dont want this to be super weird.
<bot>: girl wouldn't give me an answer when I asked for a coffee date, which I assume is a no. How should I act in class when we are sitting next to each other since she didn't answer and was super awkward.
