What is the best ending of love?

What is the happy ending of love? Many people think it is marriage and growing old together. Think about it carefully, but it's just the length of time each occupies in the other's life. Someone walked with you 15 to 25 years old, and someone walked with you from 25 to 28 years old. At the age of 28, you thought it was time to get married. At the age of 80, you found someone to accompany you. I think the happy ending of love is not to spend a lifetime together, but to spend a period of your life with you when I love you the most.
