People will come and go from your life. Regardless of how close you are, there may come a time when the relationship fizzles away. The two biggest things to keep in mind are to realize that sometimes people will become memories, and that you cannot hurt yourself trying to make sense of why that person is leaving your life. Trying to make sense of these things will tear you apart, choose instead to enjoy the good times you had, and never use previous pain as a reason to justify not opening up to new people. Just because one person has grown to let you down, does not mean that everybody will. There are good people waiting in the world to become a part of your life
