You did not screw anything up. If anything you both have a better understanding of each other (a little bit anyway). In a way crude way you were both open and honest with each other, even if it was done with anger and frustration.
I am sorry that you breakfast plans did not go through. I know all to well how it feels to have a well laid out plan go sour. You just have to plan for the best, but be ready for the worst. But, more importantly right now at this point in our relationship we have to have NO EXPECTATIONS, only our best efforts.
“Do you want to be RIGHT or want to be LOVED” “You have to have a life to share a life with someone” “When you stop resisting, you start learning”
