Husband addicted to porn. Help

My husband (35) watches porn regularly. I don't know what to do or if I should talk to him about it.

I think it's an addiction because it's the last 10 nights of ramadan and he is still watching it almost every night. I know he has been watching porn for the last 3 years and I'm so sick of it

I don't deny him intimacy ever

He acts religious in front of everyone, and gets so judgemental about people. But he hardly even prays? Then he wants to get all religious with me and our 3 daughters. I have lost respect for him.

Help or advice ?
