All the cards are open, after 11 years of living together !!!

"HOW TO LIVE NEXT"?

Hello!
Dear readers, tell me how to LIVE further if you do not want to LIVE, but stop at the very moment when you realize that you have three most beloved children all over the world and they do not need anyone but you. But the heart breaks away from the pain and suffering when you find out that the FAVORITE MAN with whom you have tied your life with everything has not loved all these years that we lived and we lived 11 years together and it turned out that all these were the years I used everything as it turned out that I was just instead of furniture, and in bed, the girl he looks at in porn films and presents it to himself.
I'm asking you very much. PLEASE, advise me how to act, I am in a strange city. I have no friends, my parents died in childhood, and I was left alone, and now with three children with my son - 10 years, daughter - 6 years, daughter - 5 months. And I have no one to turn to. Advise me "HOW TO LIVE NEXT"?
