In my relationship, there are certain things each of us tends to decide -- including booking vacations---but the idea that I'd think since I normally decide where we'll vacation with a certain chunk of money (and I am always looking for what WE'll like) means that is my money to do as I please with and can suddenly decide to spend it on some trip purely for myself and my mom (for example) leaving him out, is just not a thing I would ever consider.
Likewise, I would be hurt and angry if he told me there was no vacation budget this year because he decided to do xyz thing for himself only.
Now, if there were something one of us truly wanted to do, we'd discuss. We'd look at how WE wanted to find the money for it (cut down on vacations, but maybe also on concert going, for example) and how WE could support one or the other's big wish.
I am saddened that so many fellow DISsers apparently think I am "greedy" because I have brought very little money into our relationship but still feel everything we have is pretty much equally ours.
DH and I knew when we got married just after obtaining degrees and his was engineering and mine was teachign that our income levels would be lopsided. Then we moved immediately to where HE got the best job offer, even though that meant I'd need another year to recertify in that state before I could even use my degree. Then we had kids and both agreed I would stay home with them (for many reasons--including that new teachers do not make much more than daycare and that his boss did not take well to people calling in sick to take care of ill children, so if I were home he'd never have to do that). we moved through 5 states chasing his career and at some point realized it was silly to put money and time towards me recertifiying in the new state only to move again before I could use it, then moved abroad where our visas did not even allow me to work for the first five years.
Luckily, DH, like Gumbo, does not see me as greedy or all of the money as "his" He sees the many ways I have contributed to our partnership, including the many ways I have made it possible for him to focus on his career as he did (moving, handling ALL the house/yard stuff, appointments, etc for decades, he never once called in sick for an ill child in 20 years of being a parent . . .) and everything is OURS.
