If you want to prevent this kind of ending for your business, you should create a buy-sell agreement, or buyout agreement, which can be included as part of your partnership agreement. A buy-sell/buyout agreement helps partners decide and plan for what will happen when one partner retires, dies, becomes disabled, or leaves the partnership to pursue other interests. For example, such an agreement might allow the partners to buy out a departing partner's interest, so business can continue as usual.
