Yeah I can see it now. How she suddenly can take vacation and has money. I'm sure she wants to do it without kids but we have every other weekend to ourselves so we could've gone together at anytime.
She's going with a single girlfriend. So I'm trying to figure out what all that means? How normal is it for women to do vacations like that? She keeps saying she should be able to go on vacation and take trips with her friends. Which ok I can accept. But then you pick the one place we've talked about for a couple years now but don't have any money or vacation time to go with me?
I see nothing wrong with having a friend who is single and wanting to spend time with her, but not in a situation/on a vacation that bothers your spouse. We shouldn't do anything in marriage that hurts our spouse.
The bigger issue is your wife's view that she can do what she wants without discussing it with you, even if it bothers you.
