No, I understand where you are coming from. So should he. Him knowing your past in more details should know that even the smallest stuff could send you running. In my view, a spouse should never hurt the other spouse. If doing something hurts the spouse, that should stop. Your husband should stop looking at porn because that will only make your marriage fall more downhill given all the problems you had with your past marriage. I suggest you really talk to him about this, let him know you cannot continue on in a marriage where you are feeling hurt and betrayed. Yes, it's just porn, so he should give it up with no problem because that is not the real deal. I don't buy that whole crap, "Every man looks at it, get over it." That is not true. If he doesn't respect your feelings enough, he is not the right one for you. This is hurting you, this is destroying your marriage. He needs to decide what is more important, your marriage or the porn. I suggest you guys get into marriage counseling and you get personal counseling over your past.
My husband is a marine, had a porn addiction, and stopped because he knew our marriage is more important than that filth.
