Tad, "Unfriend" your wife on facebook. You need a safe place to post to your friends and if you are going to post there and discuss mlc, then you need to do it in peace. I wouldn't offer up a reason as to why you have done it unless she inquires.
Drop the rope totally. It's time to do so. She is pinging all over the place and she's got you doing some of it as well. You can't heal and get yourself together with her pinging all over the place. She's sucking you into her drama and YOU DO NOT NEED TO GO THERE!
You will find that you will do so much better w/less interaction from her.
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.
