Welcome. You have definately found the right place for help. There are so many resources and stories here to help you get healthy, to see the patterns that we all see, and to know that we are not crazy. One of the things I like most is that this site is divided into categories for leaving, deciding, or staying. It's nice knowing that people won't encourage us to leave our spouses, and instead help us find the tools we need to attempt to leave peaceably.
It amazes me that as I read the stories of everyone else's life that it sounds just like my life. I'd say the best place to start is with the Lessons. I've only been here about a week. I'm not even through the first Lesson but I've already learned SO MUCH that is helping.
