I cheated on my fiance and dont know if i should tell him
I am getting married in two months and I went on a girls holiday abroad and met and slept with a another guy. I was on a foursome with my friend who I went along with to make sure she was okay, but when we got back to the two guys hotel, my friend went to bed with the guy she had met and me and his friend started just kissing and stuff but we ended up having sex and us sleeping together.
My friend has told me not to tell my fiance about it but I am wracked with guilt. Should I tell him, I love him so much. I couldn't barely to lose him because of a stupid mistake.
