Hi Jamila,
You may only see the stale side of him and not the so-called great side of him because he doesn’t feel that you deserve to be shown the great side of him.
It may be due to something that turned him off in conversations that he has had with you in the past.
As a result, he may have chosen to simply use you as a source of gossip.
He doesn’t hold you on as high a regard as he does the other coworkers of whom he is more than happy to show his amazing, kind and good listener side to.
If he is affecting you this much, it may be best to ignore him.
You can still be professional and courteous if you happen to bump into each other or are working together.
However, you should probably avoid giving him gossip information or allowing yourself to show that you are being affected in any way if he decides to hover or talk to people around you because he notices that you are ignoring him.
If you are able to consistently maintain your distance from him, in time, he will either start treating you like he does the other coworkers or he will just abandon his interaction with you altogether.
