<human>: I met this girl in graduate school, I liked her instantly. As I got to know her more I fel so in love. She sat next to me in every class, parked in the same parking lot, and would walk with me to the parking lot everyday too. All that just makes me think she likes me, but I'm not the best at reading signals.

I feel like we really connect. The first time we met outside of school was because she was going to let me borrow a book, but we ended up talking for 5 and a half hours. Another time we were working on homework, which took 30 mins, but we ended up talking for 4 hours.

At the end of summer school I invited her out to a drink after class, she accepted, and we talked again for about 5 hours. Two weeks later I invite her out to lunch, we talk for just shy of 7 hours, the longest conversation of my life.

These long conversations mean a lot to me because before I met her the longest i had ever talked to anyone was like 2 hours, and I thought that was a lot. Also our conversations are fun, lots of eye contact and laughing, I just feel a strong connection and strong chemistry.

I'm torn between telling her how I feel and just keep being friends for a while more. I'm afraid if I tell her she'll stop talking to me and things will change, because that has been my experience every single time I've had feelings for someone before. I'd hate for her to stop talking to me because this is a beautiful friendship and we still have a years worth of classes together.

I'm just not sure how to approach the situation, any advice?

Sorry for the long post!
