With the utmost respect, hardygrrl:
You made it “very clear” to him that you were not the least bit attracted to him, yet you continued to be “a big flirt”. This sounds like a classic “mixed signal”. You also say you “tried to be tactful”, which I suppose means you danced around the fact that you were not attracted to him, which would only have led to his confusion.
His crime, you see, (aside from the eavesdropping, etc., which was quite lame) was persistence. Romantic comedies and cute little stories have taught men that persistence pays off, and he just has to work harder in order to win your love.
Here’s how the story would have played out in Cosmo:
“There was this guy at work…I flirted with him for most of the year, but I wasn’t really interested, since I was seeing someone online at the time. He loved coming to see me in my cube–I could never get any work done! He used any excuse he could find to touch me, and I told him to stop, but I was secretly excited. He was concerned that I was not really happy with my online BF, and I knew deep inside that he was right, but I couldn’t tell myself that at the time. Then, one day, he wrote me the sweetest letter…I had to jump his bones then and there.”
What I’m saying is that yes, you do have to wear the big flashing neon sign. You may think that you have been perfectly clear up to this point, but you may not have been. What you consider obvious he may consider ambiguous, and what you consider subtle and tactful he may miss altogether.
He does not deserve flaying, or beating with kitchen implements. He simply needs to be told, firmly, unambiguously, and without question, that you are not the least bit attracted to him, you are not going to be, you are very happy in your current relationship, and that if you can’t interact on the level of friends and co-workers, you won’t interact at all. Also tell him that if he ever eavesdrops on you again, you’ll have him strung up. Make sure he understands. Ask him if he understands.
Again, no disrespect intended. I’ve just been on the other side of the “I made it perfectly clear!” thing, so I know what can happen.
