Can a lawyer who took me on pro bono tell me to find a new lawyer, because I'm taking up too much of his time now?

Before answering your question, I would be curious how exactly you came to be a "pro bono" client of this attorney. Though you likely are already aware, just because an attorney agrees to perform services without payment up front does not mean they are performing those services for free.
Regardless of your payment arrangement, your attorney owes you ethical duties. If litigation is ongoing, your attorney may even need court approval to "withdraw" as your counsel of record.
It sounds like the best course of action for you would be to gain clarity as to how this attorney was initially retained, and to review your written agreement with the attorney. If you are dissatisfied with their services, you may want to consider addressing these issues with your attorney directly.
Best of luck!
