I am assuming you two were 50-50 partners in your venture. In which case, both of you are responsible for the profits and losses. You could sue your former business partner for the share of profits owed to you as well as for the money he used for his personal expenses under the theory of breach of contract (although there's no written contract, you two agreed to go into business together) and unjust enrichment because business funds were used for his personal expenses.
