Would you ever forgive a coworker?

A few weeks ago I got really drunk at a business function my coworker and I attended. I caused a scene and really embarrassed my coworker in front of clients and the local business community. I have said I was sorry. I have given him his space. But will he ever forgive me? I just want my friend back. But that appears broken now. How can you show someone you are sorry and will never let anything like that happen again if they won't talk to you about it? He will talk to me, just not about that night. I mean we all have done something embarrassing and dumb while drunk. My boss and other coworkers have forgiven me. But they weren't there and I didn't verbally bash them. Please advise.
