How would you react to the situation?

A man invited me to meet his teenage child from my first marriage.

I refused for a long time, but finally agreed. On the appointed day an hour before the meeting, he cancels the date, motivated by the fact that his child gave an ultimatum: "That today she was not here, I do not want to communicate with her".

I don't know how to react to this? I am so unpleasant that I lost all desire to date a man.

What would you do in my case?
