Someone who's addicted to porn, needs help from God, a church, a real friend/friends, a support group. I think some of us here are misunderstanding the role of a girlfriend.
Obviously, a porn-addict is not ready for a relationship. Can we all agree to that? If that's a yes, then there's no point arguing OP.
I'm a girl and I won't accept a boyfriend who struggles with porn. Is that judgement? No, it's called "looking to yourself, so that you too will not be tempted." Galatians 6:1
