DH and I (long before he was DH) went on holiday with two of his friends and their two small children about 8 years ago.
I thought all was fine. The second to last day, I had gone to bed and DH was sitting outside with the husband of the couple.
He didn't realise I could hear the entire conversation as so called friend slagged me off horrendously, basically saying DH could do loads better, I was immature etc etc etc.
I listened like this dreading DH saying something in agreement. He 100% stood up for me, saying he totally disagreed, how he was really happy with me
I stormed out and confronted so called friend.
Dh and I left early next morning.
We have never spoken to them again. I have suggested a reconcilliation a number of times (especially as DH is godfather to their youngest) but he has always said no, he could never forgive friend for saying those things about me.
So no, I would never holiday with friend again.
Although hearing DH say those things made me completely realise how wonderful he was and we got engaged a couple of months later.
