Pouncer - so sorry you're struggling with all that!! Wow I can really relate to a lot of what you wrote and I feel for you, feeling unwanted and self conscious due to a partners porn addiction - oh boy do I relate to that, it's an awful place to be.
My ex was constantly lying about everything too, it crushed me and left me totally confused about everything in my life. I can't imagine how much harder it'd be in a marriage where walking away is not so simple. I hope you make your wellbeing and health a priority though..
I'm sorry you're dealing with all this, I hope you keep checking in here and looking after yourself, you're amazing and I'd hate to see your husbands actions drag you down!
