I'm so much happier now, as I'm not having to be his digital guardian. I ended up taking on a role I never wanted. I did that for 5 years.
He found ways round the digital chastity locks I held the passwords to on his devices and that he asked me to put on.
Twice I forgave him. Twice I tried to work with him. Twice I tried so hard to rebuild what he had broken.
I was done when I discovered him doing it the third time.
He went for counselling after the second time I discovered his secret online life. His suggestion to go. He told me a few sessions in that he hadn't told the counsellor why he was seeing them and just said he had a problem with online porn. The sessions dribbled out and no change in behaviour occurred.
So, for me, I couldn't tolerate his lies and cheating any more. It's only up to you what you will tolerate.
Being honest, I miss my marriage, but don't miss him. I miss the friend I fell in love with. I miss having someone in my life who knew me inside and out. I'm sad he told our children precisely, in detail, why our marriage was ending. It probably gave him another kick to do so. So their dad fell off his pedestal - DD rarely sees him now, and she used to adore him. I'm so sad for them.
But, for me, life is so much better now. I'm free of working hard daily to choose to love someone who treated me, and my children, so poorly and could only see his own selfish "needs".
All the best with whatever you decide.
