I agree. Sounds like the person isn't committed. There are many reasons for that but the bottom line is they won't get you anywhere. The upside is if they're not fully into it, they're more likely to let go. I say be direct and ask that person to walk away. If you have a product and some sales you have potential. You can sell that potential to another partner (now especially that you know what to look for).
If that person is unwilling to let go, consider pulling on a third person at an equal split. I'm sure some people would disagree with that but 1) if that person won't let go, you're probably running out of options or 2) the competition might turn your current partner 'on'.
If you have a product that does sell, I would do everything I could to make it grow. You've overcome a lot of obstacles to get to that point. If you can make it grow with a third, you'll have more options down the road (like buying the second partner out).
