How long should you grieve is complicated if you read ten different opinions in ten different books. It is complicated if you listen to well-meaning family and friends.
The answer to the question of how long one should grieve is as numerous as there are hearts that are broken by personal loss. How long is a period that does not work for grieving no more than how long should you love someone.
Grief, like love, will last your lifetime. It will be intense in the beginning, then as each day turns into weeks, then months, your grief will find a place in your life. As long as you live, you will remember your loved one…and you will grieve.
