Upset!!!

So I've been married to my husband for 3 years now and we dated for 2 years before that. After we got married I had found out that he is addicted to porn. We've had several fights over it since then and he knows how I feel about it. I've tried to spice up our sex life and we have sex almost every day. I thought I had fixed the problem but today I was helping him reset a password for one of his accounts and when I opened his browser there it was. Idk what to do. All I know is it's a horrible feeling knowing I don't please him.
