Your logical thoughts are VERY valid and normal. Logically speaking, abusers do not validate emotions or normal logical thought. I believe that you have likely said everything and done everything you can to this point.
I can only tell you what worked for me when I was in a similar situation. I gave myself permission to grieve the loss of a relationship. I gave myself permission to want better than the relationship where I wasn't important, loved or treated with respect.
I gave myself permission to feel anger and I self validated my anger. I crushed and broke things at my local recycling center and gave my anger a voice. Eventually., after saying everything I was angry at my abuser for doing, saying, I said out loud I was angry at myself for not standing up for myself sooner and for believing my abuser for 20 years. That's when I worked on forgiving myself.

I hope the hurt you feel fades quickly. I hope the emotional validation you need comes to you. I hope that you can accept my thanks for reminding me how far I have come in my own journey to healing from abuse. I have no doubt that you will heal with time.
