I can't even convey to you how sorry I am for what you are going through. I have been through a similar situation where my loved one was--and still is--addicted to pornography and masturbation and I thought the pain I felt would kill me. I still really struggle with how much it hurts me.
My heart bleeds for you and I hope so much that you can find the comfort you need. Please get whatever kind of help that could help you both; therapy through the Church, talking with the bishop, or whatever you need to do that will help you get to a healthier emotional state. Being married to a porn addict has such devastating effects and creates wounds that cut into our souls.

I wish I knew how to help.
