Wendy, Please do not look at her FB page again. It is causing you a lot of sorrow and you do not need that. She is very much aware that you are looking at it and that's why she's not blocked you yet. She wants you to feel miserable.
As for the 5-7 year comment about getting over a long term marriage...well, I was married for 25 years and it took me approximately 2.5 years to get over it. Why? Because my xh was the horse's @ss in mlc and I had enough of his bs. Also, my xh was not the poster boy for being a husband either, however, I accepted him for who he was and we did have a good life, but my life got even better once we were divorced and I had recovered my balance. I never knew just how often I was making excuses for his behavior or the "walking on eggshells" that I did. The divorce took a huge burden off of my shoulders and I have never looked back.
Hang in there and please don't allow the ow to push your buttons this week. This is your week to do whatever you want and enjoy your time while your h is away.
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.
