When you choose to forgive the same people over and over again you do so because you don't want to believe your time loving them was wasted. Bad relationships over time can become investments, that are hard to let go of. The key to freedom is to realize that love is never wasted. The only thing wasted in life is the time you spend focusing on an unhappy situation that will never change to fit your needs, and not realizing the true investment of time and love are the lessons God wanted you to learn.
