<human>: A few months ago, one of my friends went through a bad breakup. We weren't super close at the time but we started hanging out a lot. Soon we become pretty close and flirty with each other, and I start to crush on her, so I was going to ask her out.

Before I could she off handedly mentioned that she had started seeing someone, who is now her boyfriend. She still acts pretty flirty with me, and I enjoy being friends with her, but I feel lIke she led me on and I am starting to resent her a little.

I want to tell her how I feel, so I can at least start to move on a little knowing whether or not she has any feelings for me, but she is in a new relationship now and it may not be the best idea. However, it still pains me to be crushing on her when she isn't available and I want to do something to try and get over her.

Provide a brief overview of the text.
<bot>: I thought my friend was into me, but now she has a boyfriend and I'm still crushing on her. Should I tell her how I feel to try and move on?
