Is it possible to play the long game? I.e., before your partner tanks the business, lay the groundwork for you alone to rebuild it from the ashes. E.g., make sure you have copies of all the source code, and any other intangible assets. After the business tanks and he too is short on cash, buy out all claims he has on those assets, and restart the business? Also consider including your investor in the planning. He/she might be more willing to help you save the business at your partner's expense, if the alternative is losing their entire investment.
