I don’t know why and how I have such an huge affect on this (married) guy but it’s not funny anymore, at first I thought he was playing now I doubt?

Reason why I start to think that is bc for example: ( we work together by the way) first of all he is still fairly new guy I’ve been here for over a year maybe little more or less and he just came a month or so, the first day he came he was the first one to randomly come up to me and he asked if I was ukranian and I said yes and after that that’s when it all started. Not sure if it’s bc of this main reason he got interested in me but I will say one thing I’m definitely not the most attractive woman and I am little overweight, I saw his wife in photos and she’s like a model with a nice body so that’s another reason why I’m clueless what made him get attracted to me, but basically he always tries talking to me asked for my snap, asked me one time to sit next to him at break and often times calls me by my name and even called me Mrs… and even sang a little sentence on my bday that happened to fall on the day we worked. And he did admit he is married, so what I’m trying to ask is do y’all think I’m just overthinking? And maybe he is just playing around without really having anything to do with me outside of work just prob very bored and wants to play with my emotions or is he actually serious anytime can you help please
