My husband was an a cheating site

I posted a few days ago that I had been noticing my husband clearing his history on safari everyday for about two weeks, but I could tell from his screen timing he had been on safari early in the morning and during his lunch hour. So whatever he was doing online was at this time. A woman here called me creepy for checking on him but I felt in my heart something wasn’t right. I can’t describe the feeling but something just told me to look. Anyway, yesterday I got home and again checked his phone. He had been on a porn site and then it showed he was on adult friend finder. com for eight minutes. I confronted him and he said he had been watching porn but got so angry about that site saying he had no idea what I was talking about that he wouldn’t be on any site meeting those kinds of people. I know for a fact this man goes straight to work and comes straight home everyday so I know he hasn’t met with anyone. But I don’t know if he wasn’t actually texting someone there. He is the kind of person that will tell you things as it is and straight up told me he likes to watch porn once in a while and there is nothing wrong with it and he won’t stop. My question is if he was on a porn site could it have shown as if he was on adultfriendfinder as a pop up. How could I find if he actually has an account there? I know I read you have to pay for that site and he is not the type to pay for any websites nor does he use a debit card for anything. He pays everything cash. Please someone that knows about this stuff help. I did leave him yesterday and went to my parents home. He says I’ve overreacted. We have a 2 year old and it breaks my heart for him because throughout the night he would cry wanting to go home.

Update: Lisa, yes I left him. I was hurt thinking he was talking to women because he did that to me three years ago when I was pregnant through Facebook messenger with a woman from Chicago. I haven’t seen anything since but when I saw that site on his history I felt so hurt. Sure he didn’t physically cheat but it still hurt.
