Search Results: spark a conversation

Midway through last year, I got transferred to a new base location at work. When I got there, this girl who did sales for my department was really into me, but I had eyes on a different girl who worked with her. But I never acted on it cause she was 5 years younger, and was all about her tinder life and was constantly getting hit up by thirsty guys, so I thought it was a waste of time.
The other girl initiated conversation and proposed us going out and we went in a date and it was good, but it could have been better. She said she wanted to do it again, but never responded to when I asked her, so after a while I stopped talking to her, she started attention seeking and I just deleted her number.
She's been bitter about it, and she had wondered why I went out with her, she thought I liked the other girl.
The other day, the younger girl came back from a few months of being ill, and she was very happy to see me and was really enthusiastic in the time I saw her.
The one male there said I should have gone after her cause he claims to have seen a spark between us.

By the way, I don't work with them, they just do sales and I'm not involved at all.
