I slept with my husbands best friend

We all live together. They work together and sometimes I wonder if he ever feels bad for sleeping with me. I wasn’t with my husband at the time.....but my husband doesn’t know about it.

Update: So I followed y’alls advice and told my husband. He didn’t even care since It was back in high school and none of us knew eachother yet besides me and the guy. He just laughed and admitted to sleeping with my Bestfriend back in highschool....before of course I met him. Some of you ladies are rude. It doesnt make me a bad person that I slept with a boy when I was 17 that happened to become Bestfriends with my now husband through work and has moved in with us since hes on hard times. It was just a small innocent confession. Y’all are really weird.
