I'm not passed that yet since I'm still living with him and learning the tools. I'm sure I'll feel different once I remove myself from the situation.
Maybe you will, maybe you won't.
I stayed and I worked on me. I figured that 1) I needed to have some stability/sanity before I could make a major decision like seperation and 2) I was definetely part of the "problem" by the way I was treating my husband, talking to him, carrying on, etc. I focused on me and getting myself... and much to my surprise, things got better.
More importantly, when I stopped telling my husband what to do, he was able to figure things out on his own. I learned how to treat him like an adult and let him be responsible for his actions/choices.
