Tad,
Sure you know why you are sad. You are looking at the calendar and thinking about your xh and the fact that she's getting married this Saturday. I'm sure it's on your mind 24/7 and you know what? Maybe w/her getting married, you will finally be able to let her go and put your focus full time on your sons, mother and you.

Tad, let her go.


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.
