I just recently ended a 28 year marriage.... feel very much for you. Sex, making love was not the issue with us. We mentally separated 10 years earlier and this ended up in physical and emotional abuse.
My thought... if it is not working and you are unhappy. Make a change

This will be super difficult, but better than having the entire county cop department in your front yard.
Think about you. Porn is not you. Huggles
