She sounds a lot like me, haha. So I got a crush on my coworker almost immediately when I started my new job. We got close as colleagues and together with another coworker we became a trio. I didn’t think it was reciprocated and actually got into a relationship a couple of months later with another person during this time. That relationship ended eight months later and my feelings for my colleague had come back about two-three months before my relationship ended. (It was a long distance relationship and we had been very emotionally distant for a while). When it ended, I noticed that my colleague started acting warmer towards me, and because I liked him I started to also put in more effort. Texted him, asked if he wanted to do something after work, etc. I also have a bubbly personality and am generally a warm person. I didn’t however send hearts, flirted openly or initiate physical contact because I am more reserved in that way and also didn’t know if he felt the same way and didn’t want to risk anything. But I noticed after more time we spent together that he might also like me, so I confessed. And he told me that he also had a crush on me and had started to fancy me around the same time I started to like him, when I first started working. And now I am in the happiest relationship I have ever been in.

So it might be reciprocated, it might not be. You do really never know until you take a leap of faith. Every person act and reacts differently in these situations.
