<human>: I recently saw someone I had known years ago in a way that seemed quite serendipitous at the time. Nothing 
happened, life went on as usual. And yet, I feel as though this event has warped my mind somewhat. I loved him for the entire time that I even remotely interacted with him. Yes, he was pretty, and all the other girls 
were aware of this and tried to take advantage. I really, truly just loved this person, flaws and all. It 
genuinely seemed at times that the attraction was mutual, but I digress. Once again, life happened. he made his choices, I made mine. I NEVER stopped thinking of him. Over the years, I would Google him on occasion, even when I was in a relationship and married. My mind is like a steel trap, especially when I am searching and 
researching. I retain tiny details and then apply them in further searches. One night I "over-Googled" and  discovered that he had spent some time with debilitating depression, I would say a year or two. Most people would 
be swayed by this information, but I wasn't. I have spent many years battling depression and mood swings, 
and I know how that can impact one's existence. I can relate to these things, and I know that not many 
people can.I know my details are boring Reddit, but I have been keeping this to myself all week, unable to explain it to anyone out of a sense of my own embarrassment. My questions, if you have made it through my silly post....
Does this feeling, this sense of longing for the company of a past love/interest ever go away?Is this kind of thing productive? Have anyone of you or someone you know ever had a happy ending come of this? I'm not even looing to date this person on the regular, I just want to see him, get a cup of coffee, simple shit like that...

Could you distill the essence of the text into 1-3 sentences?
<bot>: Saw someone I loved from years ago quite randomly. Now I can't get them off my mind. Does anyone else
