Don't overthink it. If you were diagnosed stage 4 brain cancer, you'd just leave now, and no one would be upset. People are upset for a day, and then they move on (see OpenAI?). Leave now. If the investors think the team can succeed, they'll invest, if not they won't invest. Full stop. The future is your co-founder's problem. You can also leave just after the raise, it's really as you wish. Investors know the drill. They know you could be hit by a bus 2 minutes after signing the check. Don't listen to whoever tells you what to do and what not to do. If people remain angry against you, well they just haven't understood the rules of the game. Be free.
