I miss my friend

It's been almost 4 weeks now. I used to play games in the evening and have some relaxing times with my friend. I'd get a good night message from time to time and comments about things that I bounced off my friend. Now all I hear is a dull thud when my messages don't get answered.  We've played ONCE in the 3 and a half weeks.  Yeah, I miss him as a lover, but I also miss him as a friend. Sad thing is, I don't think he misses me at all.  Or I don't think he realizes how different things are on this end. Does that make the last 3 years of our friendship worthless if he doesn't realize how much its changed?
