We keep our personal funds separate. For mutual items, electric bill, taxes, new roof etc, we both pitch in to a joint account. It’s been working great now for the last 38 years. If she comes home with a pair of $500 boots, it’s her money and I don’t care. If I come home with a $2500 pistol, or whatever, it’s my money and she doesn’t care. I don’t have to “get away” with anything. It’s my money so she doesn’t need to worry over it and I don’t worry over her funds.

But that’s what we do and it works well. Congrats on the new goodies, if you commingle funds, you might consider a “run away from home fund”. That’s where you stuff a bunch of cash away she doesn’t know about, then if you have goodies to buy or you choose to split up, there’s less pressure.
