Thinking about relationships

Recently I have been thinking about interpersonal relationships . I figured out that once people are psychologically hurt by others ,they will not want to communicate with that person who hurts them. And then their relationship are getting worse and worse even end. This is how we lost our friend. When we meet that situation ,what we can do to repair our relationships is a complicated question. Most of the time we just let things go. So it reminds us to cherish the friends we have now.
