I'm so sorry you're going through this. I know exactly how you're feeling because I've been through it. Still am going through the fall out.
My H was not only constantly lying about watching porn, but was also looking up prostitutes online. I hated the poem but I couldn't help feel a new line had been crossed.
After a year of everything settling down and me believing the problem of porn had gone away, I discovered he'd been viewing prostitutes on Twitter, a woman in a city he is due to visit soon.
To cut a long story short, after constantly demanding the truth in order for our relationship to be saved, he first admitted that years ago he and his friends used to go to a brothel. The women would dance and they'd pick who they wanted.
He said it happened 6 times and the only reason he still looked at P's online was because he was curious (& also now saying he has a porn addiction). This didn't make sense to me because surely his curiosity had already been satisfied.
I continued on my demand for truth. He admitted that he looked up the website to the brothel to look for the girls he slept with in the past (in a different country where he use to live). He admitted that he used to use sites like Adult Work, would hook up with a girl on advice of others and be fascinated with linking up what others had said about her.
He admitted that he had considered going back to the brothel if he was ever back in his country visiting.
I continued down the line that I felt there was more to it and that I needed the truth before I could move on (I was lying to get the truth out of him). He then admitted to returning to the brothel when we were engaged and we were applying for a fiancé visa. He swore he didn't sleep with anyone because he loved me too much & didn't want to put my health at risk.
He lied.
I finally got him to admit he slept with a P while we were engaged. That's when I threw him out, about 2 weeks ago. I'll never know for sure if he slept with anyone here but it doesn't matter. He tells me he's a changed man. A changed man doesn't spend his time looking at prostitutes. He has no true remorse, he can't, or he wouldn't have kept looking.
I don't know your situation fully but when I posted here about my problem (before I knew he'd cheated on me when engaged), a very wise woman posted to say that the only people who look up P's are the ones using them. I didn't want to believe her but she was right.
You have a sense that there's more to it. Trust your instincts. And NEVER underestimate their ability to lie. I have been absolutely blown away at my H's lies that eventually unravelled.
I'm so so sorry you're going through this, I really am. Just be very careful. Only you can decide what to do next, whether it's to confront him again or wait until you have more evidence. My H had gotten very good at hiding his trail and was very careless at the beginning so don't take that as a sign of innocence. But eventually he slipped up.
