YR, I'm very happy to see that your fathe made it through the first surgery. He will make it through the second as well. Your father is a fighter and will make it through the next surgery. I think you are very wise in waiting until he returns home. Your parents will need your assistance and support at that time.
As always, keeping you and your family in my thoughts and prayers. The waiting is actually harder on you and the family than on your father.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
