You're the boss. You made mistakes. Stop. Take his perspective as far you can.

Do what must be done. If necessary, go public yourself and see whose attention your project gets. Adapt/pivot accordingly.

If he already threatened you, he's about to do it or will do it at some point in the near future, when you lost/invested even more.

Don't waste money you don't have and more importantly, don't waste time and attention.

You fucked up. It's your mistake. Own it, drink it off, adapt.
