Middle aged, married mother of teens here!
I recently went on a European city break with two female friends, one single with no kids, the other in similar situation to myself, if relevant. It was very sensible - sightseeing and a few nice meals & drinks.
I happened to mention it to elderly neighbour who looked shocked and said "and your DH was happy with that?" and said that her husband would never have allowed it. I took it with a pinch of salt given her age when she then said that her daughter in law had done similar and her son (in his 40s) was not happy at all but let her go in the end. I made a mental note that her son must be a chauvenist and forgot about it.
Then, a few days later, I met with a friend who is the same age as me and has kids in their late teens and early 20s. Subject of my trip came up and she seemed genuinely shocked and said her husband would not be happy at all if she did that. I said that was ridiculous, that my husband had no problem and I didn't expect otherwise. I half seriously suggested that we organise something ourselves but her reaction told me it was an absolute no no!
I have to say I was shocked by these attitudes in this day and age! Surely this isn't the norm amongst middle aged men, or is it?
