<human>: Recently things have changed a bit between me and a girl I met via a common activity, namely that we began to talk more often, went out to dinner with friends, and went to a party together.

Following this, she has been messaging, texting, and snapchatting me much more often than previously, and, when we were eating with a few of her friends, she made several different jokes over the course of about an hour about us being a couple.

I've not been actively seeking her attention, but neither have I pushed back- I've responded in kind, as a friend. She's a great girl, quite pretty, and honestly anyone would be lucky to be with her.

That said, I am a terrible human being. Back when I first met her, my friends and I would poke fun at her accent and her odd use of certain words (English being her second language) behind her back, something which we did intermittently until only just recently. In addition, when I first caught on to her increasing attention towards me, I dismissed it to my friend, telling him I wasn't 'into that'.

I feel awful. While at this point I'm not sure if I'd want to be anything but friends with her, I feel absolutely awful that I made fun of and dismissed offhand this great girl that has been nothing but a good friend to me. Honestly, I'm not really sure if there's a solution to this, but I want to get it off my chest.

Can you summarize the given text in a few sentences?
<bot>: Aquaintance-become-friend might be into me and has been nothing but nice to me. I dismissed her affection and poked fun at her English behind her back.
