There are times we have to let go of people because, for any number of reasons, they grow distant, they outgrow their need, or desire to have us in their lives. No matter how much it hurts, let them go. No matter who they are to you, husband, lover, adult child, let them go. Don't be the albatross who holds them back, but do not sit pining, and wait for them to return. Release in light and love, go forth knowing you did all you could do, find happiness within yourself. Move forward knowing it is the right thing to do.
