As an evolving soul, you are coming ever closer to utilizing love in all the many facets of your being.
When you can release past situations and hurts, you are not only giving yourself the freedom to progress on your path, but you are liberating the other souls involved.
By disengaging, you are letting the Universe take away uncertainty, doubt, and regret, and when those negative emotions are gone you have the power to replace them with hope, belief, and contentment.
Detachment also assists in bringing you back to your center and creates a sense of calm and stillness.
By being in this state of equilibrium, you are not making an admission of failure or giving in.
