I was found out, about five years after it ended.
I was 20 and living at home. Our married neighbour, friend of the family, policeman started visiting us, during his work breaks. He would drop by, saying if he went home it would just disturb his DC’s right on bedtime.
I honestly thought, as did my parents, that he was visiting them. My dad asked him to ‘keep on eye on me’ whilst they were abroad for three weeks, so the visits continued. He asked me to go with him on an ‘undercover’ job to a local pub. Told me his wife couldn’t join him. I was so naive I met him outside our houses and went on the ‘job’ with him.
He and I went out together for about two years, going for a drink maybe once or twice a month. I didn’t ever sleep with him.
I had other male friends in that time, who he and his wife met. I ended this friendship when I met my husband. I told my husband about my married friend (who he worked with too). We married.
About two years into my marriage my married friend’s wife was told that he was having an affair with the school gate mother of one of his DC’s friends.
His wife told him to leave, but once they started to try and work things out, she wanted him to tell her everything so that they could start again without any lies.
That is when I was mentioned. I got an out of the blue panicked call from my married friend, asking me to corroborate what he had said.
They stayed together and are still together.
My DH threatened to leave me, we had just had our first baby. I was devastated and unable to put right what I had done years previously.
However, we also worked through it and had a second and third child…(until my husband had an affair with a female colleague and left me!
‘Come-uppance’ maybe?
(I didn’t find out and had no suspicions, until he confessed. Hindsight is a great thing!)
