So I've met a new man, I'm 22 and he's 25 and we've only been dating for a few months now but I really like him and he's recently taken me home to meet his family as he's not from my area originally.
I met his younger brother and to my surprise I discover that when i was in university roughly two years ago, I actually slept with his brother and one of his friends at the same time. I know that he remembers this as we've spoken about it and he's agreed not to tell my boyfriend and give me the choice of telling him or not.
What should i do?! if i tell him, i might lose him for good.
