ohhh boy. Here's a new one, please help!

So a few nights ago I was talking to a (male) friend that I was close to since middle school but haven't seen face-to-face in about 5 years. He's drunk, and proceeds to tell me that he wished he'd made a move on me back in high school, and that his life had turned out differently. He's been married for 6 years to someone we both went to high school with, and apparently they first started talking when they ended up in the same town for college and he wanted advice about me. Well it's no wonder she's hated me for years! But...what do I do with him now? I can't un-hear all of that! And neither can his wife! Why do people do stuff like this?

Bleh...thanks guys.
