Your W is not fully lost to you...but you need to continue moving forward. Notice, I didn't say "moving on". Moving forward, to me, means continuing to live your life and doing things that you enjoy. It means experiencing new and exciting things along the way, as you leave the door ajar and a candle in the window to guide your W home.
Some will return...and it usually happens when they see their spouses moving forward and living life to the fullest. When you let them go totally, i.e., heart, soul, mind and body...they know it and that's when many of them begin to wake up and slowly reconnect.
You and only you can decide what is best for you and your situation. No matter the outcome, you will be the one to make the final decision on the matter.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
