If a married man at work is overall very nice to a woman and his not looking for a wife does it mean he is just trying to be a friendly guy?

There is this guy married and over all very nice to me and always communicates with me at work but he won’t like hit on or flirt completely he just super nice but the thing is I’m not here to make any friends with opposite gender I will be nice and respectful and greet but that’s all I will make same gender friends bc I had a situation where a married man led me on and I didn’t ask for it and it ended up bad one time so this guy is like trying to be a friend to me but I don’t want this kinda attention would it be alright if maybe I just respectfully tell him hey listen I understand you are a nice friendly guy but I’m not looking to make any friends so we can just leave it as work associates?
