I’m lost and confused not sure if this married guy at work is just a friendly guy who might come off as a flirt not intentionally but I may be wrong?

Either way he is 29 and I am 25, he has been married for about 6-7 years and has two twin girls and I’ve seen his wife on Facebook she’s beautiful with a nice body, so why I’m asking is bc the first day he started working i remember he came up to me randomly and introduced himself and was like ohh you’re pretty good at what you doing huh, then that’s how it started off, than the next day during break he comes up again starts talking again and that’s when i noticed he had a ring and I asked if his married he didn’t hide it and said yes and said he has two kids and that he goes to church bc I mentioned I go to a church as well so than I start thinking okay his “Christian” maybe he just a friendly guy who seems like his flirting, but then he stops me again when I was walking and starts asking me about my relationship and if I’m single or not and I said no I’m praying for the right man and he was like you will get an answer. Then he wanted to ask me if I thought he looks good I was like umm I can’t answer that bc you are married, and just I can go on and on he would come up to me and say oh you doing a good job I would just thank him, then I was walking to clock out and I guess he was behind me and his like ohh you walk so fast. Than later on it was my bday and I was working that day he hasn’t spoke to me yet but my friend mentioned that he told her that he still had to wish me a happy birthday, so on break I was sitting and I see him come he randomly starts singing happy birthday, and when I was walking out with my friend after break he was already at his place he started singing again , so I don't know y’all 🤷‍♀️ but few days later when it was my friends bday we was walking and I was like are you going I sing for her bc he knows we always together he turns around and looks and kinda starts singing and then stops I wanted to see his reaction. But yea kinda weird huh
