<human>: Can you condense the text into a few key points?

Hey reddit, so I started talking with this girl i met on facebook because we shared the same interests in sports, music and stuff like that so I texted her during one of the LA Kings game and we really hit it off. We were joking with each other sending each other funny videos and I was a bit flirty and she too was flirty so I was going to ask her out but I found out through a mutual friend that she has a boyfriend. That honestly made me feel like shit because this is the first girl i really like in my school in a long time and now knowing it won't happen kills me. I don't want to remain just friends because I know how I feel about her and I can't shut it off so should I just stop talking to her and find a new girl? And why was she flirting with me back if she is in a relationship??? Help
<bot>: I'm flirting with a cute girl. She flirts back even though she has a boyfriend. Should I stop talking to her?
