have to attend to sleep so not able to post much right now.
Just a reminder that detaching doesn't have to mean NC. It is as much about getting yourself off the emotional roller coaster. If you can be in her presence and have convo with her without getting sucked in, that is the goal...
It doesn't seem you're 100% there, yet. Not sure how many really do get to that point. We can't be ambivalent, we have history with our spouses.
Keep working at it, it gets easier.
As far as IT work, I understand. I'm not disabled, but having primarily a independent consultant for the past 15 years, it's hard to impress a company that you can be a long term, capable and quality empolyee... I'm looking at job alternatives...
Good luck with that. Something will come up for you.
