Okay am I overthinking this all or not?

There is this one married guy his like 3 years older than me, his a nice guy but I don't know if his being friendly or too friendly for a married man, for instance he will ask me how to say this or that in my language he will often times say good job what would this “job” do without you etc we can chat quite bit sometimes more sometimes less he will ask me me for some favors but it’s been almost a year and that’s just how it’s been, I doubt if he wanted to cheat on his wife he would already done it, he hasn’t asked to hang out side of work type of thing just seems like sometimes he likes the attention at work, people even start joking asking where is you’re boyfriend? Referring to him etc should I just stop talking to him or knowing nothing will happen just interact at work either way? Am I overthinking this?
