Do you ever get hung up on someone you nearly dated?

I met this girl not too long ago flirted a bunch was at first going to be a hookup but I expressed an interest in taking her out for a date, she agreed and it warmed up to a point she came round to mine told me she had a crush on me face-to-face.

I rushed things along overdid the flirting so when I scheduled a date she pulled back, but we kept as friends even saying we'll keep that door open between us as a never-say-never.

Still hung up on her though, tonight she went on a date with someone and I won't lie I feel pretty shitty. I've been trying to shake my feelings for her for some time now and it's hard, especially that she's part of the same friend group as me I don't get really get a chance to not be around her.
