I held a meeting with my client and I told him that I had enough work at the new rate to fill my work week (which was true) and that I didn't want to create a situation where I prioritize some client work over other client word because of the different levels of pay. The client wanted to keep the same rate and quality of service that I had been providing so he agreed. He told me that he obviously wasn't happy with it but that I was worth it. I went into the meeting with two options that I would be happy with: not continuing work for that client, or working at a much higher rate.
