Nope, just depends on the person and his/her purpose..
In the OP's case, her husband doesn't want to go but gave her his blessings so that's actually better than cases where one spouse lies to the other so he/she can cheat. And again, it doesn't even have to be at a club..
Yep, it's like I mentioned to him.
There are girls who will go and not tell their spouse at all.. I would not want that as to why I will tell him where and when and with whom.
Yes, he admits sometimes it does bug him that I go, because then it leaves him home with nothing to do but I explained to him that he doesn't have to stay home when I am out, that he can come with and if he chooses not to then he's always more then welcome to hang out with his friends.
