I messed up

I'm devastated because I hurt the person that I love the most. I'm not proud of it but porn and the lack of self control has ruined what I love the most. I've always had a problem watching porn but it got out of hand when I started using the live chats and paying to watch someone lived just to release myself because I'm by myself or just cause. I thought I could manage it and change, but thinks just got worse. I was forgiven on other occasions by my wife for watching, or having pictures of other woman, but paying on I live chat.... My wife was gonna use my phone to see some pictures that I took of our kids and found a screenshot that I took. I've been married 11 years and I love my wife with all my heart and I do this. I feel disgusted of myself, empty, I had no words other than disappointed of myself. My wife is the best mother, my best friend and I hurt her and made her feel like trash. I want to save my marriage, I want to change and be a better version of myself. This addiction, this rush is destroying what I love the most. I want to overcome this issue, I need to change.
