8 years ago I went through exactly this situation.
I was 50/50 shareholder, voting rights and co-director in a bootstrapped startup with no shareholder agreement. I worked as the CTO building the product for 4 years and hired a team of 4 other developers. My co-founder hired a full time salesperson who eventually left when he couldn't make quota. I was 21 when we started the business, he was 31, and over those 4 years I just grew up to realise he wasn't a good CEO.
After multiple failed attempts to raise money I eventually called one of the investors to ask for honest feedback why he didn't invest, he told me the vast majority of his failed deals happen when co-founders fall out and predicted that would happen with us too. I decided 3 months after that email to leave the business.
I started a new company with a similar product but focussed on large/enterprise in that market, while the previous company was focussed more on small clients. I kept my shareholding but resigned as a director. The co-founder went nuclear and decided to dilute me out of the business by issuing new shares and buying them. If I had bought them I would have just been giving him the money which he'd just pay himself as a bonus and then repeat, so I just had to watch my shareholding go down to 25%. All legal avenues I went down just confirmed that the cost of litigation would cost more than whatever I'd get out of it.
The year before i left my Grandad died and left me $15k and at the time I decided to forego my salary for 8 months to help the company's cash flow situation. So I eventually offered a settlement where I would sell out of the company for $15k and be done with it.
Forward to now, my new company, still bootstrapped, is over $10M ARR and profitable with 113 employees growing at 60% a year. I have over 51% of the shareholding and over 60% of voting shares. I still write code every day and behave more of an engineer now than I ever did in the previous company.
My advice to you is to take the money and leave, start something new and just start building. You have already realised the biggest value of that company; lessons about what to look for in a future co-founder, how to run a company and build a product. Leave everything else behind, move on and I promise you'll look back at this moment in 4 years time as being the best decision you ever made.
Good luck!

Man this is inspiring - No expectations or anything but Id love to learn more about this journey!

Agree with that, I now know what to look for if I started a new venture. Thanks a lot for sharing your story!
Not OP, but found this very helpful in my current situation. Thank you for sharing.
