<human>: I met this girl at a soccer game about three weeks ago, and that was just a brief "Hello, nice to meet you". Fast forward one week, I see her at a football game and it turns out we both have a close mutual friend. End up spending some time, have a fun night.

Later that night I get a text from a random number and sure enough its her saying she asked our friend for my number. At this point, I am kind of interested so I am thinking "Cool! This could be good". Well, its not looking too good.

We've been talking non-stop since that football game and we have both developed feelings for each other, but this was before she brought up her boyfriend. Of 2 years.

I asked about the whole situation and she basically told me that she lost feelings for him a while ago and wasn't sure that she wanted to call things off with him, but after meeting me she had pretty much made her decision. A few days go by and they are still together and she still talks to me non-stop.

I see her in the hallways a lot and I text her throughout school, and I constantly get things like "Oh I would, but you-know-who is with me."

I really was starting to like this girl and I still do, but this whole situation is making me uncomfortable and I don't want to ruin anything for that guy. I have absolutely no clue what to do because I want to continue talking to her but something is clearly wrong with this situation.

To add, I am not leaving matters unattended. I have brought this up to her several times and nearly every single time I do she responds with something along the lines of "Oh, I don't have feelings for him anymore its really okay". I really like her, but I'm trying to put myself in her boyfriends shoes (whom I don't know) and its just killing me.

Summarize the given text in a few sentences.
<bot>: Girl and I like each other, her boyfriend doesn't know, I have no clue what to say because she acts like its nothing and says she lost feelings for him. What do I do?
