AGONY: She called me to apologise for sleeping with my husband

I thought I had the best man in the world. Even though we have been married for 11 years, he's love for me seemed to always be blossoming. In fact, my friends never miss a chance to remind me how lucky I am to have such a good and faithful husband and father of our three children.  

But all this was proven a lie when a certain chic called me last Saturday afternoon when I was chilling with my friends to apologise to me for having slept with my husband since December 2018.

She claimed to be a fresh graduate working at my husband's office. And that since she found true love and settled with her husband to be, she felt compelled to apologise to me for fear that the same might happen in her marriage. I tried to defend my husband but she backed her allegation with Whatsapp messages, pictures and videos while they were making out with him.

I'm too stressed, lost appetite; feel annoyed and betrayed but fear to confront him. Should I just pack my bags and go?
