I ended up calling him yesterday and apologizing for my email, and my relentless pursuit for his perfection. LOL!
What came next, blew me away. He told me that he hasn't been practicing any of the band's material outside of rehearsals, because he just views the band as a reason to get together with friends and get away from the girlfriend.
His reasoning is that when they lost their first drummer and lead singer earlier this year, it took the wind out of his sails. They weren't able to keep gigging and make money. He said that he isn't very motivated to put much time in because he fears that it will happen all over again. He also told me that he doesn't care for the song much.
Sounds like you need to have a pow wow with the whole band to find out what their motivation is. Do they want to gig or just be a garage band? In the same type situation after a year and a half I quit the band because I had other money making gigs and didn't have time to just fool around.
