In my case, I actually pushed for my wife to leave even though I didn't really want her to go, but I felt like it was time for her to go. Unexpectedly, I found that my life was much better and brighter after she left. The eggshells were gone. I could get things done. It was miraculous.
A couple of weeks after my wife moved out, my anger started to escalate. My fog was clearing. I started to clearly see how poorly I'd been treated. She was a bully. She'd rubbed my nose in sh*t for a long time. After that, I'd resolved not be treated like a doormat by her ever again. I could clearly see that I had to live my life for myself and my sons and she'd have to find her own way.
I don't know if you'll have the same experience I had, but I suspect you will. As abysmal as it may seem right now, you have a bright future ahead of you; this is just a bump in the road.
