It seems like we have almost a perfect marriage, other than the arguments over money. He is the type of person to almost completely ignore necessities to get what he wants, because that's the way that his parents are, along with nearly everyone else in his family. That's why even his 70+ grandparents are still working. Whenever I try to sit down and talk to him about it, he gets very upset and angry. I don't know how to get through to him that we need to save nearly every penny we get, because we currently don't have any extra finances at all, and our baby is due at the end of March. I feel like if it was between getting diapers and buying a new video game, he'd choose the video game.
One major thing that makes it very difficult is the fact that he is the only one with a job and is working. He feels that since it's "his money" as he puts it, he should get to do what he wants with it. He doesn't seem to realize that he's not a kid anymore, and, even though we both have had to grow up fast lately, that he has responsibilities, and can't do whatever he wants.
I'm not saying that I want to cut out everything he wants to do for himself. I'm not saying that at all, and he doesn't seem to understand that I'd be perfectly fine with him spending money on things he wants, when we actually have the extra money for it. I just want him to realize that his responsibilities and his family's necessities come before what he wants.
How do I get him to understand without upsetting or angering him?
