I recently found myself in a situation (about 7 months ago) where a married man that I know through work had displayed interest in me. I rejected his advances and suggested that we keep it on a professional level and he agreed. However, when I've seen him a few times since and each time, he makes really prolonged eye contact with me, both from across a room and when speaking to me. It's very unnerving! I personally that he says one thing (happy to keep thing professional), but with the level of eye contact, he's maybe trying to instigate something or sound me out for having a potential affair with him. Am I imagining this?
