My Question is What should I do when my husband wants to look Porn instead of wanting to make love to me?

I have caught my husband many times looking at porn instead of making love to me and he has turned me down then to only look at porn after I went to bed. I have told him so many times how much it bothers me when he does that but it feels like it goes in one ear and out the other. I Just want to feel like I am the only one he needs and the internet does not control his life.
