NC'd for this.
My close friend got married at the beginning of this year, I was a bridesmaid and DP was an usher (he is also close friends with the groom).
The other day, a different friend of mine came over and the subject of strip clubs came up (in reference to stag nights) in which my DP admitted (of his own accord) that he had visited one on the above mentioned groom's stag night.
He didn't mention this to me at the time, just said they'd all got roaring drunk in town. I'd never probed further as DP has never given me cause to doubt his word- well, until now!
Afterwards, I asked DP why he hadn't mentioned it previously - he said all the party had agreed not to say anything as my friend (the bride) is extremely against it. The groom was bought a private dance by the party.
Whilst I was annoyed with DP for keeping this from me at the time (and find these clubs a bit seedy - the men who go in, not the dancers). I didn't think there was really an issue to be had here. DP is genuinely lovely and really did offer this up himself, there's no way I would have known about this or 'caught him out' otherwise.
Sorry getting a bit long!
Anyway, my friend who was there the other night now thinks (very strongly) that I should tell the bride what happened that night, that it was unfair for the groom not to give his bride the choice to 'know who she was truly marrying'.
I think the deed is done, they are married now and other than cause a row that needn't occur - it isn't my business?
