Why Can't You Let Go

This story is my true story. The story started when he and I had a diagonal table, and we talked about everything. As a result, he moved on to a better place, and I was still lingering in the same place, hoping that he would come back to me. In fact, I scolded him many times, deleted and added him back and forth many times. I don't know why I can't let go. It's obvious that he is not good at all, but I still care.
