Pandora's box has it right, and so has everyone else who's advising you to communicate. it's one thing to take a time-out to think things over, but if you don't talk, you'll never get anything resolved.

Basically, your friend has given you bad advise. "Avoid him until he says all he's feeling to me, and if he doesn't, just don't talk to him again." Let's think about that. If you're avoiding him, how's he going to tell you anything? My ex-girlfriend pulled this crap on me and it did was leave me feeling (four and a half years later) like things STILL aren't resolved between us. She's moved on, but I haven't been able to, and I may never be able to.

Ask questions -- specific questions. Listen to his answers. Tell him how you feel and why you're feeling that way. Ask again if you aren't getting relevant answers. Don't let him walk away until you've said all you came to say, and you've heard all that he has to say. You may not be happy, but you'll have closure.

And the question you should've asked is, "Is a friend ever wrong?" Yes, they are.
