Hello need help

Hello,
I was here at this site a year ago, I am back, and need to participate. 11 year relationship, his secret life, and 100s of sexual encounters came to light a year and a half ago. It has been a horrible nightmare since that. I have done much research, and am totally aware of what I am dealing with. No one, except one who has experienced this kind of manipulation, and mind control could understand.
I have lost 65 lbs in the last year, I am wearing a heart monitor for 30 days, due to recurring chest pains. I believe this is "broken heart syndrome". I am weak, confused, and isolated. He bombards me constantly with his devious intensions. He is an empty soul, evil.
Long story short, I know only one thing for sure right now. I must remove myself from him now.
Complicated but must be done.
I'm not really sure how to navigate this site, or where. To find stuff to help me through.
Thanx,
deb
