My husband watches porn everyday

Looking for advice. I’ve come to find that my husband watches porn every day. He waits until I leave for work or errands and gets right on the computer. I never had an issue with knowing that he looked at porn every once in awhile but now that I know it’s EVERY day I am feeling awful about it. We have a good relationship and a great sex life. Sometimes we can go a week without sex depending on our schedules but usually we have it every day or every other day. Knowing that he does this as soon as I leave is very discomforting. Everytime I bring it up to him he gets very defensive and denies that he looks everyday (I have proof though). He doesn’t like to talk about it and that makes it worse for me. I don’t know what to do bc it really upsets and bothers me. Has anyone else been in a similar situation? Any advice? Thanks
