Anyway, he never did look! Except at used cars and trucks. And that is one rivalry I can handle.
@OP If he is looking at porn, he needs counselling. Porn is highly addictive. Just because he is a Christian, doesn't mean he can't get pulled into that dance of death. He needs an accountablity partner, and to be confronted by men in the church, particularly men who have been through this temptation, and out the other side. (Many pastors get sucked into porn! Most of the major evangelical denominations have set up counseling services for pastors involved in porn! I had to take this in seminary, although it meant nothing to me personally, I now understand why God wanted me to know this information!)
It is possible to change, and to break free. But he needs to want help. And you can't be a nag about this, as much as it hurts. I hope you are able to get him directed into counselling. And prayers for the new baby that should be coming this week!
