I am new too but I have to say I was in your shoes. I was in my 20’s when I first found out that my husband had an issue. He went to counseling, 12 step groups for 2 years and we both believed he was better. Not so. 30 years later I found out he has been cheating on me for years. You see that porn addiction escalated to prostitutes.
I wish I had a crystal ball. Consider me yours. Run and don’t look back. Sell the house and move on. You are worthy of a better life. Why spend the rest of your life in doubt. Checking phones and computers. That’s no way to live. There are plenty of men out there without this issue. Just thank God you didn’t have children with him because that changes everything. You’re free. I wish someone told me that back then. All I heard was about forgiveness. You can forgive but save your sanity and go.
