If a friend of yours has actually been secretly or unconsciously wanted to walk away from the friendship for a while then it's best they do so. You only want to keep relationships in your life that are thriving, that they are genuine. You don't want to maintain your grasp on a friendship where one person is fundamentally unhappy with it for one reason or another, or one person doesn't want to give the amount of energy and commitment that you do. Sometimes even if it hurts and it's shocking and we thought it would never happen, when a friendship ends it is actually, absolutely the right thing for us, because if they have had any doubt in their mind that the friendship wasn't right for them or beneficial for them, it's always best for us if they walk away. We don't want to continue to maintain friendships that allow them to linger, if there is something rotting that we never knew of. If we keep those kind of friendships in our life that are not built on a foundation of trust and mutual benefit, something is going to blow up in our faces.
