Kissed my boss!? HELP

I have been in this job for nearly a year and ever since the first day I walked in I have fancied this one co worker. We have good banter and we get on well. But I had a boyfriend at the time and so it was just a crush.

A month a go me and my boyfriend went on a break, 2 weeks into this break we went on a work night out and after finding out I was on a break he started flirting with me all night and made his move and kissed me!!! I had no idea he was interested in me at all and I thought I’d made it obvious all year that I fancied him!!

The only attention I’d got from all year was general chit chat or the odd comment about my saucing dancing videos😂😅 As soon as he found out we were on a break he was super flirty with me on this night out, he teamed us together when playing pool against some other colleges and let me hold his arms so I could walk in my shoes all before we kissed. Afterwards he chatted with me for ages whilst still kissing me several times, danced with me and held my hand whilst walking between bars. He even kissed me goodbye.

He messaged me the next day to see how I was but that was it. After a few days at work, once me and my boyfriend had officially split up and once the slight awkwardness had passed between us at work I messaged and asked him where his head was at. He said that we get on and he wants to “keep it that way”, and doesn’t see anything more than that here.

He only recently became my boss so I’m wondering if he’s just being professional or if there’s potential for more to evolve here. Opinions!?
