Would you be upset if your husband had a close female friend at work?

I became close friends with this man at work who happens to be a married man his like 16 years older than me and has 3 kids yet I’m single so I don’t even find at slightly attractive just conversation wise, I’ve trained him quite a few times and we seem to get along well and even sit at lunch together and basically chit chat a lot we are not on the same team so I don’t always see him but if we are working the same days we always come across each other is that too much?
