I've experienced some aspects of this before and I know it can be difficult. The longer it goes on, the more set into the current deal you are and its very difficult to change.

One way it could be made easier is if there was an independent reference point. E.g. can you afford to hire an employee? (1) This employee could pick up some of the work and it would presumably have to be paid for 50/50 and (2) If you are still putting in many more hours than your co-founder then you can log those additional hours and you should at least get paid a similar amount that you are paying to the third employee.
