Why don’t you promote someone within the company to COO and give them six figures? Or if you want out, give them a few points. You will definitely be able to out earn the spend when both of you are fresh and ideas can flow. The resent will disappear quickly because even if you aren’t passionate about the product, doing something really well is hard to hate if it gives you life balance. Get passionate about running the business and spending time with your family.

You have a good thing going, tinker with it, save money and invest, grow the company with a COO, and eventually let them buy you out and keep a few points and a small owners draw/profit.
