Dear Coleen

MY HUSBAND of 20 years has been having an affair with a woman from work. He blames me for this situation, saying I have been horrible to him for the past 18 months so he has sought solace elsewhere.

He thinks this woman he has known for eight weeks will make him happy for the rest of his life and he wants to leave me and move in with her.

I found her profile on Facebook and messaged her asking her to leave my husband alone.

We met and she is the total cliche of a younger woman in an unhappy relationship, going after her married boss.

We chatted for three hours and I explained to her he wasn’t the lovely bloke she thought he was and there was another side to him. I also told her we had been intimate when he told her our marriage was dead. I showed her a photo of us cuddling on the sofa.

That evening my husband and I were making love, but got interrupted by this woman, texting him to say it was over and that she was leaving work too. My husband was furious and blamed me for ruining everything.

He has now moved into the spare room and swings between depression and anger.

What can I do to repair this situation and remind him of our love for each other?

He sent me a message today saying he just wants me to leave him alone as his health is suffering and his blood pressure is sky high. I should add, he also had an affair with a younger co-worker 10 years ago, which lasted seven months before he came back to me again.
