He often “brags” about how his life used to be and all of the things he accomplished. He speaks of the same things over and over.  It is all about him. He is recently out of rehab for drug addiction and all he can talk about is a “big, huge, comeback” he has planned. And how he is meeting with a realtor about the “most amazing condo”.  He speaks of how he loves southern women and European women...constantly. He is also constantly pulling people he just sees on the sidewalk and gets someone to take pics of them together to post on social media. As a friend, I am trying to figure out what he may have so I can understand him better.  I know he is delusional and I feel bad because I feel like it is a coping mechanism. But at the same time it is exhausting. 
His family has disowned him due to his stealing from them. 
At the end of the day, I know he could care less about me. He is super self absorbed; it’s all about him, his (non-existent) career, and finding a girlfriend. 
Any ideas?
