A married coworker has been chasing me for months, After tying to let the situation fade away because he's married, I finally gave in a started flirting back. I am attracted to the man but I do know it's not an ideal situation to be in. We have texted and DM each other flirty messages. We went on a few lunch dates and exchanged a few kisses. He kept asking for nudes, not something I do, but he sent me some so I gave in and sent him a few back. Now he seems to be pulling back. What has happened here?
