I second the opinion of getting a therapist, it is someone who you can confide in and will help guide you in working towards your new path. My dr listened to me for years and when that straw was finally laid upon my back, I had my dr to help me articulate what I wanted and needed. She did not tell me to get a divorce but simply said if I made that decision she would support me. Although when I told about a violent act he did towards the end, both she and my pdoc were telling me to leave the house. Honestly, she and another friend are what got me through that time, it's only been two years since I made the decision to leave.
Definitely coming here to PC is good to, just to have someone to listen to you and sometimes talk to others.
Take care.
