Men - Confessions

I am a 33 year old male,engaged,and I have been addicted to porn and anything sexual since the age of twelve. I have asked God to help me out of this too many times to count,but im still in this same place. Im living with my fiance,also sin,and watching porn with her or alone daily. I am a believer and I feel God is probly not even hearing me anymore. Anyone got a response for me?
