Ask HN: Toxic cofounder, considering leaving the country. Thoughs/legal advice?

Hi,

We're a DE C-corp and cofounder relationship is toxic without any sign of possible improvement. I am the product and programming side, toxic cofounder is biz dev and I don't need him to build awesome product (already vetted in market). I want to leave and start my own/take the idea elsewhere abroad if necessary.

Has anyone else been in this situation? What are the legal ramifications? Thanks
