I was in your place nearly a year ago. Been together 20 years, we had drifted apart abit, but i thought we were solid.
Found out about his EA with a mutual friend that he always fancied. Huge row when i found out and he dropped the bomb shell that he doesnt love me and only as a friend. Absolutely destroyed me.
Nearly a year later we are still together. It has not been easy at all. He was vile to me in the months after, he was not sorry he had been caught and would only say that they were just friends and it would never had gone anywhere, but he changed her name on his phone, say his name is John Smith, he changed her name to Mrs Smith on his phone and sent her kiss emojis and called her beautiful.
I made him stop all contact with her and he was really resistant to this. Deleted her off facebook, we had a huge row as he didnt want to but did in the end.
So, a year later, he has actually apologised to me, thinks it was depression and has now come out of the other side.
Things will never go back to how they were, i have sorted out my finances, reconnect with friends and go out more. I think in hindsight he was never going to leave, i asked him to on 3 separate occasions and he wouldnt go.
I still think about it daily and feel sad and angry in equal measures. Will we make it another 20 years? I dont know. Will I ever totally forgive him? No.
But one thing, he will never do it to me again, one whiff of anything and he is out of the door, if i can survive what he put me through i can survive anything.
