Well, I had hope to find someone who was right for me, meaning who didn't mind my addiction. But that is not how it will play out. Hashem will not give up on you like that. He will find you a wife who is perfect for you, for you-after-you-are-better. And through the marriage you will get better. This is important to understand because pornography you can kick, but you may view your wife as your sex slave, she will know that before you even get into bed, and that is the final problem that you will eventually have to get over.

I think it's irrelevant whether you tell her or not. A wife is already lined up for you.
