Thanks for your (and everyone else who has commented here) advise. I think the approach I am going to take is to see if he's willing to sign an agreement to dissolve our partnership, giving me 100% of the company. If he really has just grown tired of it, as I suspect, I think he might do this. If he's not willing I'm going to try some type of buyout, payable once revenues can pay for it. Then I'll offer a small stake as a last resort. If he's unwilling to accept that then I guess I'll just have to quit the company. I really don't want to do that, I've spent so much time on this :( . But I'm also not willing to keep working on it without my fair share of the company; I'd rather start from scratch again on a different idea.
