Husband is addicted to pornography

Husband is addicted to pornography: My husband is a Christian. He views porn online for hours each day. He masturbates to pleasure himself. I have caught him several times. We have talked about it, but he sees NOTHING wrong with it. I share my feelings about how it makes me feel. I feel unloved and unattractive. It is affecting me deeply, I am always available to him. I tell him this often. I am affective person and show him my love for him frequently. How can I resolve this huge friction in our marriage? Please pray for us.
