I'm so sorry. This happened to me in 2003. I just had to accept it and move on with my own life.
I was devastated at the time but eventually, I realized that I did deserve better than what he had been giving me, and was able to pull myself together.
I wish I could give you better advice. I know it is so painful. All I can say is that you'll be ok. Be good to yourself, allow yourself to feel the emotions and celebrate your strength as you deal with the pain and move forward.
I'm sorry this is happening to you.
hugs
Angel
