Of course I don't really understand the situation, having just casually read what you've posted here, but .. it all seems dubious. I think, despite the possible upside of having a dedicated US sales partner, that it would be safer to cut all ties with him as nicely but definitively as possible, and just move on. Unfortunately, you will have to accept that it's likely he will say bad things about your company and your product when he has the opportunity. But I think that will likely be a small price to pay: nothing you've described sounds like good-faith, transparent, mutual benefit business which is what you should expect from a partner. Best of luck!
