<human>: Provide a brief overview of the text.

A couple of days ago, I made a post in r/needafriend. I received a LOT of responses but there was one person who I got to know that really, really peaked my interest. Not quite in a romantic manner but as a friend. Let's call him Dave. Dave was married and had children with his wife. He was not used to having women as friends because he knew nothing other than his wife. 

Dave was also in recovery. I can't share with what because I feel like I would be breaching a level of trust between us. Anyway, he decided to talk to his "mentor" about the relationship between him and I. His mentor had suggested to him that he doesn't feel he
s in a position to be trying to build a friendship with me right now. He took his mentor's advice and said goodbye abruptly to me last night. I am at a loss because I feel like I've never had such a genuine friendship in my life. I feel heartbroken. I know I am usually the person who's giving the advice but I truly don't know what to do.
<bot>: Had an amazing friendship like nothing I've ever had before and it was ended abruptly due to mentor's advice. What should I do? Should I try to talk to him about it or let it be?
