to Las Vegas with his friends behind my back.
I discovered this by accident when I was forwarding some photos he took on his phone to my phone when I spotted the 'Vegas' group, which had been archived, presumably so I wouldn't see it! I felt hurt that he has not discussed it with me first as we will have a newborn at the time they plan to go. And also as his friends were saying to book it without telling me, it left a nasty taste in my mouth.
DH has several holidays a year and has been away with friends before and I have never stood in his way, but I felt upset by this trip being planned behind my back.
What would you do if it was your DH?
