Guy's Behavior

Slept with a coworker and now another one wants me?

I've been sleeping with one of my coworkers for months. We really aren't coworkers cause he works overnight and I work open-mid shift. We've been sleeping together for months without anyone finding out or noticing. This guy who also works overnight has started to like me to suddenly. I don't work with this guy either and he works the guy i sleep with shift. i only saw him once and he just said hello to me like a normal coworker and went his way. That was like 4 months ago, i haven't seen him in person since. Out of the blue he follow me on instagram. I'm not following any of my coworkers on anything. I also have my name on my social media which he viewed one day. I cut off the coworker im sleeping with recently after a disagreement and the next day the guy followed me on insta and viewing it everyday. I asked the coworker im sleeping with has he told him about us but he it was a no. He's not my type and i dont want him but its obviously he wants me badly. How do i get him to stop?
