I am dating a woman who I love more than anything. while going out I've looked at some p***graphic material and paid for some material and imagined it was her and I together. I feel like I've cheated on her and I am so ashamed.
don't let the shame define you, don't let it feel so bad that you go and do it again, it's a endless loop and leads to brokenness and emptiness. Porn is the opposite of love. It's so hard to avoid these days but it is possible and worth it. You may need to seek a program of help, lots out there - search for local help, either in a group of others that struggle or 1:1 w a paid therapist. I'll tell you that these things don't just "go away" without working on yourself. I continue to struggle but am working on myself too.
Don’t let shame find you. Confess your sense of God and he will forgive you. Pornography is one of the most evil things in the world, and it creates perverted people.
