I have to say that I agree with others there are significant structural issues with the benevolent dictatorship type governance model. A team of people with diverse skills, strengths, weaknesses, commitments and all that is needed to bring a project like this to its potential.
Establishing a committee of some sort to share the work is really going to allow your efforts to shine to a greater degree and highlight your contributions, not diminish them. Perhaps getting in touch with some organization like Software Freedom Conservancy for advice? They exist to help with this sort of thing:
Conservancy assists FLOSS project leaders by handling all matters other than software development and documentation, so the developers can focus on what they do best: improving the software for the public good.
