Pornography Addict

I resent my husband. He is a porn addict. The other day I came home from work early and the moment I walked in the house the phone sex wowan was calling him back. I felt the anxiety in my stomach and demanded his phone. He lied and said that he didn't know who she was. After a few moments he confessed that he "had a moment of weakness." He also admimitted viewing the porn on the computer, thats the reason he was logging off when I came in. I feel like a fool for trusting him. I really believed my marriage was improving, but it wasn't. I want to expose him before the church, out of anger and not love. He has a leading position, but he is a phony.
