There is a girl in one of my classes (started Wed) who I have a slight interest in (she is very attractive) but in the first two class periods it has already become weird for me. I'll try to make this as succinct as I can, but I may not be too successful.
The first day of class I went in and without thinking about it sat next to her (I just looked at the people sitting on the row and tried to sit where I had a seat distance from everyone). The teacher then insisted that everyone find a "partner", so then we were partners.
After class ended I asked her why the teacher wanted people to find partners, if there was there was some sort of project later on the course (she had taken the professor for the prerequisite). She said no, and I then commented on how I thought it was strange that the teacher insisted that partners exchange emails and phone numbers. After I made that comment she said "you can lookup my email in the online class directory and study".
Her being an attractive woman, I assumed she thought I was prying for her contact information, so I "corrected" the situation by saying "no, I just thought it was strange that the teacher was insistent on exchanging emails" (thinking I was making her more comfortable by enforcing the fact that I wasn't trying to get her information). I thought it was strange that she offered up her information and mentioned studying (she could have just said "no, there isn't any group work, I don't know why she wanted people to exchange contact information), which to me could possibly be a sign on interest, but the way she offered her contact information sounded almost like a tactful way to defuse what she could have perceived as a uncomfortable situation.
The next day I came in, sat down and simply asked her how it was going, nothing special. I didn't say anything else (or really look her way or anything) and then when the professor left the room to get some papers she turned to me and asked how my second class was the day before. I told her about it and said that the professor kept calling this one person out for being on her phone and she said something along the lines of: "oh my goodness! My face would have turned so red, I would have been so embarrassed!" which I thought was a rather exaggerated comment.
While we were doing practice problems I made a couple short comments about off-topic stuff (nothing weird or out of the ordinary either) and she responded but in my opinion, rather awkwardly. After class I asked her if she had done anything interesting the day before while I was in my second class (since she had started asking me about things first) and she responded rather enthusiastically with a handful of things that weren't really all that out of the ordinary (for example, she told me about having lunch with one of her girl friends, but didn't have an interesting story to go along with it or anything).
But when I said what I had done the rest of the day (told her our team had a softball tournament) she acted fairly strange, almost as if she had misheard me and thought I had been talking about some esoteric subject. The only other thing I could think of is she didn't hear me at all and thought I was just standing around waiting to follow her out of the room or something (worst case scenario). I just assumed she heard what I said so I just tried to finish off the conservation by saying that we had to wait another month until softball started again.
I don't even remember if she responded after that, and if she did it was probably something as short as "oh". Then she just kept walking out of the room with me and the rest of the class and left. I made sure to pull back and let her get a few feet ahead of me because I definitely didn't want her to think I was following her. At this point I was extremely confused as to how an enthusiastic response in which she gave lots of information she didn't have to give (e.g. she could have said "no, nothing that interesting" instead) let to a super awkward situation.
It almost seems as if she is switching between being overly friendly/flirtatious/enthusiastic and being really uncomfortable/nervous from conversation to conservation... To be quite honest I don't think I've ever encountered a situation like this. What is likely going on? Could there be some other reason I'm unaware of that she keeps acting uncomfortable/nervous for seemingly no reason? If I made her uncomfortable why would she have initiated a conservation with me?
