Married 15 years 2 children. Partner has been seeing the mum of one of our children’s friends for a few months. I found out by reading phone (naughty I know) he has said it was simply a turned head, I know it is more than that. They speak constantly, message, meet up. However our relationship is strong we parent well together, enjoy each others company and have great sex. Am I crazy to think he’ll come to his senses and end the affair?! I don’t want to loose my marriage. Am I being a mug??
