“There's a colleague of mine who likes someone else. Unfortunately, I had a crush on him, but I've moved on. We're still colleagues, though. I wouldn't call him a friend because he likes talking about himself and rarely asks about my well-being. I try not to have any expectations, but the problem is that he constantly talks about his crush, who doesn't even look at him or talk to him. He gets depressed about it and ends up sharing all those feelings with me. Sometimes, I feel like I'm just his emotional dumping ground.”

Stop being available for him. Like you told, y’all are just colleagues, not friends. Learn to draw boundaries for your own well being.

well pretty much yeah cuz as per his psychology, you are the only one available and who listens to him so maybe just try to be busy or go with someone else just a few times and if he really values you he would wait or come back to you trying to connect more often....I know it can be tough but you are just someone free to him so try making your distance clear
