I (34M) recently received a substantial inheritance from my grandparents who passed away last year.

We’re talking about close to 200k which is not life changing money but still definitely significant.
My wife (32F) and I have been married for 6 years and have always had joint finances.

We both make similar salaries and contribute equally to our household expenses, mortgage, vacations, etc.
When I received this inheritance, I decided to keep it in a separate account under just my name.

My plan is to use some for investing, some for home renovations we’ve been wanting to do, and save the rest for our future kids college funds. I’m not hiding anything cuz she knows exactly how much it is and what I’m planning.
The issue is this: My wife thinks all the money should go into our joint account because “we’re married and everything should be shared.” She says by keeping it separate, I’m sending the message that I don’t trust her or see us as a true partnership. I explained that this money is emotionally significant to me as it’s from my grandparents who practically raised me and I want to honor their memory by managing it carefully. I’ve assured her I’ll use it for our benefit, but I want final say on how it’s allocated.
Things have been very tense at home. My parents think I’m in the right since it’s an inheritance, but her family is siding with her.

AITAH for wanting to keep this inheritance separate from our joint finances?
