I had an affair,
I was very lonely in my marriage.
It was a new work colleague, who flirted with me, took me out for lunch when we were working, sent me links to things around my hobby, took me for a drink after work, listened to me, showed an interest in me as a person, bought my favourite chocolate to the office for me.
I told my husband, before anything had actually happened and he left. I was so angry with him, I needed him to take it as a wake up call that all the problems we had been having, and my unhappiness needed his attention, that we needed to do something, make changes but he didn't.
So I allowed the colleague to take me out, and let it happen.
It felt so good to be noticed.
So then when my husband wanted to try again I felt it was too late.
