Partnerships are one of the hardest things in the world to make work. They take a lot of patience and understanding with the other person and a lot of communication.
Most times they fail because the communication is not there or the partners are going in 2 different directions.
I just dissolved a partnership recently and I think my ex-partner and I are better friends now then ever. Plus we both got what we wanted and will most likely work with each other again in the future.
