I was in a similar situation exactly two months ago. As others have stated here, COMMUNICATE with your cofounder. Express what you are thinking and how you view the situation. My cofounder didn't. He immediately tried to push me away from the company and eventually removed me 'without cause'. We are in a legal battle right now. Even to this day I still don't know what or why he did what he did.

Communication is key in any relationship. If you can't manup and talk to them, you are part of the problem.

If after you two talk and there is no movement, then seek out other alternatives. But always try to keep an open line of communication. Sometimes the alternative is way too costly.
