I have this co worker that's starting to get on my nerves. I work in big building and he works in different department from me so I don't work with him everyday since I am casual and don't have a permanent position on one floor. I float on different floor replacing the full time workers. I am friendly with him and whenever we see each other in the building or in the parking lot we say hi to each other. However,whenever we do work in the same floor he always make remarks of me and telling me that I need a man. It all started when he asked me if I go to gym and I said yes and he asked why I then told him that I enjoy it and I like to stay in shape. He then said all you need is a man, he will do the job as a joke .I told him that I have someone in my life and that's not the point.

Now when ever I see him he insist that I don't have a man despite telling him before that I am seeing someone else. He said he doesn't believe it .I don't know why he cares weather I am single or not .He always bring it up whenever I work with him. Last time when he was leaving the floor going in the elevator he said ``I found a boyfriend for you, you have been alone for too long then he went into the elevator .

Its starting to get on nerves because I am type of person who don't like to discuss my personal life regarding who I am dating at work expect with close friends outside work.I don't see how that has anything to do with him. I am not interested in dating him and I have never showed any interest in him .I just treat him just like how I treat other co workers.

Should I tell him that my personal life is none of his business?
