As an active Christian who's dealt with your husband's issue let me offer this:
1. He will not change until he understands that he will lose his family over this. I strongly suggest you move in with a family friend, with the kids, tell him it's because of the strippers/porn and break all contact for 2 weeks.
2. Do not answer calls, emails or texts.
3. After 2 weeks ask to meet him at a neutral location. Discuss meeting with a counsellour to discuss your marital issues. If he does not change then you will have to decide how you want to proceed.
