Like @Anika66 says, the info provided here is scanty for us to give informed advice. However, you say you started having problems when business picked up, what problems were these and whose fault was it?If you were at fault, then you should think of apologizing to your partner and asking to mend things. Chances are he may just ask that he gives you your share and you part ways amicably. If it was his fault, then it means you swallowed a bait, he was counting on you leaving because of that disagreement. It also seems he ensured you don't have much evidence to take him to court or he knows you won't take him to court one way or another. So, surprise him. Try to find out some leverage that he did not expect and have your lawyer call him about the charges. See how this plays out.
For better advice, try answering the following questions so wazuans can understand the background:
1. Was the partnership registered?
2. How was handling the transactions?
3. How did you transfer your capital for the business? Did u directly send it to the supplier or did u send it to your partner's bank or was it just cash transfer off the books to your partner?
4. Do you have any email exchanges/sms or phone conversation suggesting you were in partnership?
5. What is your relationship with this person apart from the business?
Answer this, and we can try to help.
