Listen the quicker you stop these conversations with your W the better off you'll be.
Give her need to know stuff with regards to D and nothing else.
She will make you responsible for all the craziness in her head and lay her guilt at your feet.
You are not responsible for her. Her choices.
You are responsible for yours so let's put your attention there.
In what ways did you screw up? What were her complaints against you? I haven't read through your whole thread so forgive me if I'm asking something you have covered here already.
This is a process and if you haven't read the resources not the top of this forum you still have homework.
I understand your wanting to run away. All of us wanted to do that. That is the easy road. So is letting the anger toward your wife eat you up. It also easy to try and kiss her @ss back into a relationship with you. That won't work and if it did you wouldn't want to be in THAT relationship.
So take a deep breath.... You just got kicked in the jimmy and it hurts.
Now
Get the mirror out and take a good look at that poor guy in the mirror. What do you see? How do you feel about that guy?
No excuses. Don't blame your wife for that face in the mirror.
You.
My goal is to some day be the person my dog thinks I am
