Often I am contacted by people who have been left in relationship and they are desperate to get the person back. Why? If someone does not want to be with me why would I want to force them to?
Love is not about coercing someone into something they do not want to do. Love is setting someone free if that is what he or she wants even if they did make a promise to stay.
Just because we are left does not mean we are not good enough. It simply means he or she was not the right person for us. Our self-love and respect depends on accepting that when someone leaves, even if that is for another person, it is for the best, even if we cannot in the present moment see how that can be true. One day we will.
