Sometimes depressed people think they fall in love when they're just desperate and unhappy and looking for a self esteem boost. Maybe that's what happened with his weird softball EA. Now he's realized it wasn't real, and that he's made a mess of his life because of his moods. Regardless, it still brings you back to: and what is he going to do about it? You can't fix it for him if you wanted to because you are not in his mind and you don't own his problem. All you could possibly do is buy him a self help book or kindly suggest he get counseling assistance for himself. You literally can't fix his feeling crazy and like a loser.
