how did the different steps of relationship dissolution apply?

Please watch the two videos and answer these 3 questions clearly. You can make up stories. Focus on the questions and answer each one. I need this to be done as soon as possible. It is easy and I did it twice but my instructor told me This ( in #2, what type of uncertainty was at play? Or in #3, how did the different steps of relationship dissolution apply? Make sure to reference each theory and step, define it, and apply it accordingly)
