<human>: There's this girl I've been friends with for a couple of years, and we share a lot of interests and she's really one of my best friends. I've always been sorta interested in her, since she's exactly my type, so I've been playfully flirting with her since the beginning of our friendship. She has been completely obvious to most attempts, but as I got to know her better, I also learned that she really wasn't interested in girls. I accepted this, but I kept teasing her from time to time.

Over the years, others started to notice, and we got several comments form people saying they could feel 'gay vibes' from us. Since I've always been quite open about my sexuality (I'm bisexual), I always brushed it off, saying that I was probably the cause. My friend never seemed bothered by it, and so our friendship continued.

A week ago, one of our teachers decided it was necessary to point out in front of the whole class how in love I looked with her. I was absolutely mortified, and quite certain that she would, at least for a little while, keep her distance from me. To my surprise, she started talking to me even more, and we've been talking on whatapp for at least two hours every day since, while we used to talk for that amount of time just once a week before. She even actually flirted back with me, which is something she'd never done before, but when I playfully asked her if she was now into girls, she responded with "haha, you wish :P". So I suppose I'm getting some mixed signals? Or am I just looking too much into this?

(Also, sorry for my English. I'm not a native speaker)

Can you condense the text into a few key points?
