I'm going to tell this guy that he handled our situation immaturely
Why do you want to tell him about it?
I think my needs are more important than his.
I hear you, but it is rude to treat others as inferior and childish. You should talk with him as an adult, otherwise he will not want to take you seriously in the future.
I'm just saying how I feel. I think I have a right to do that now.
When you talk to others it is expected that you treat them with respect so be careful how you speak or what you call him.
