Too persistent for a person, can't let go, how to change?

The hardest thing in life is to let go, which is easier said than done. Only those who have experienced it can understand the sadness and pain. Whoever leaves lives the same way, and the earth turns the same way without anyone. My obsession is too deep to let go, and naturally I can't let go. Sometimes you have to have it in your life, and you can't always insist on it. There are people in my heart who can't let go, just like first love. What you can't get is always good. Once vowed to each other, in exchange for their own travel. I can only say that time can dilute everything and is the best medicine. Without her, you still expect your friends and family, and you still have a responsibility. I think the person you can't let go of doesn't want to see you live a decadent life. For yourself, for your family, or for her, you must live in the present! Keep this beautiful memory in my heart, and meet her with a smile and a simple greeting several years later. Recalling that I was too stubborn and naive.
