During my wild days in the university nine years ago I had a brief fling with a guy I met through a friend. We had séx a few times and saw each other for about a month before we lost touch.Fast forward eight years later; my immediate younger sister introduced this same guy to me as her boyfriend. I was hoping they would break up so he wouldn’t be an issue between my sister and I but that didn’t happen.
I have been avoiding him since he hooked up with my sister but now that they are about to be married, I’m stuck.
Should I tell my sister what happened between us or leave things the way they are? Does she have a right to know?
