Be kind, be clear, be firm. No anger needed. Just a clear expression of your requests (spell out a path forward for him that will really work for you - ask for 100% of what you want, not just some appeasements) and a willingness to be done. That will speak very loudly.
Agreed!! Ask for exactly what you would like, in your situation you are perfectly reasonable in asking for those requests!
