I wholeheartedly agree with Chester White above.
I’m not in the same situation (The Missus stays home to raise the little one) but I’ll offer the advice that Dear Old Dad gave me with regards to money:
Pool it.
Every couple that my parents knew who got married but kept separate finances got divorced. Every single one. If you start thinking in terms of “these dollars are mine, those dollars are yours” you pave the road to resentment, because one person will always be making more than the other.
And never get into a mindset where you feel like you have to ask permission to spend money. You don’t ask for permission, you discuss. You say “I want X” and the both of you see if you can work it into the budget together. That’s not getting permission. That’s behaving like a responsible adult and realizing that your decisions affect other people.
