I have to empathize with you a great deal. I have also experienced living with a man who was obsessed with pornography. I went to few love addictions groups to try to work out my own issues and concerns about living with someone obsessed with porn. I had all the same or similar feelings of not being attractive, desirable, a real woman and I hated the porn as well as his obsession with it.
One thing I learned over time was to take my interest about what he was doing and focus more on myself and what I needed and wanted. I started to realize more and more that the obsession he had did not have to be my problem or my focus in life and that I could have higher regard for myself, love myself, and value myself in such a way as to not let his behavior change me into someone I was not, and someone I did not deserve to be. I concentrated on taking care of me, loving and valuing me.
I don’t know if that helps. I have a cat to run to take care of or I would say a bit more. Many blessings and hopes for strength to grow in your life.
