First, do not dissolve the business....the corporate dissolution documentation requires that the shareholder make a representation that the obligations of the corporation have been provided for....the result of that would be to potentially open you up to personal exposure to liabilities that would otherwise be restricted to your corporation.
Second, I would not jump into personal bankruptcy yet. The money that you owe personally must be committed to a judgment and then collected. Many times being judgment proof is sufficient to keep the creditors from coming after you aggressively. If they do, you can then always seek bankruptcy protection to get these judgments erased.
Third, if your partner's new business becomes successful, you should still consider filing a civil suit against her and her company for breach of fiduciary duty and conversion of corporate assets and opportunity to her own personal good. You must file this suit within the applicable statute of limitations period.
I hope this has given you the guidance you were seeking. I wish you the best of luck!
