Me and Dp have a couple friend who are due to get married. Dp wasn't on the stag do but heard from others that the groom to be cheated on his fiancé. He's spoke to him and he admitted he had.
Dp has told me in confidence and thinks we should stay out of it, that his friend is really sorry and not usually that type of man, blah blah blah....
But I'm friends with the fiancé and if it was me I'd definitely want to know before I married him.
Dp thinks what we tell each other should stay between us and that I'd be unreasonable to say something and get his friend in trouble and in the process damage their friendship.
I think if he didn't want me to say anything he shouldn't have told me at all. Where as Dp said he'd see that as keeping secrets from me and wouldn't want to have to do that.
We ended up having a argument about it and he basically said it wasn't anything to do with me and he'd be really angry if I say something to her.
