Do you know why you did it? Just for peace of mind. To this end, you can also do other things that you think can show your mind, that is, wake up in the middle of the night and go to her window to wake her up (but it is conceivable that the result will be tragic).
There are many things in life, and you can't get satisfactory results without hard work. Only hard work can reassure people. When you can only lie in bed and remember after many years, you can calmly say that I have tried my best. As for whether you can forget, it depends on whether the time is long enough to heal the scars in your heart.
