she needs to understand Porn is addictive to even begin to try to understand its you not her and that you are a better person.
And this is not easy to grasp as a female.
If like me at the time of discovery NOT confession hating you and or being mad and or BOTH right now is not necessarily the end of the world,because if she didn't care she would not be in the bed with you or just BE GONE! ( as Ive seen happen)
Let her feel her feelings and at the same time if you cant say how you feel verbally or without conflict then write them in a letter a hand written not computer typed letter and tell her how much you care and sorry you are , as you sound like you are.
Daily letters helped me! And that was unlike my SO to write letters.
Now i think its therapeutic for him and he may not even see that his time he used to PMO he is now using to write feelings. Win win
Right now i bet she is shocked and devastated, whether its shown threw sadness or anger.
And you created this so by taken action you are trying to fix it and by her seeing that maybe- but not over night will come around.
But in some cases sorry fellas sometimes its to late!
Hope in your case its not.
Good luck!
