She wants my bank password. Is this love or see-finish loading?

So my girlfriend of 2 years just dropped the bomb that I should give her access to my bank app. She said it's about trust and transparency. I told her my money is not her business until we sign that marriage certificate. Now she dey vex like I slapped her mama.

Why I'm not comfortable

First of all, see-finish is real in this country. I have seen too many guys finish themselves because of girlfriend. One of my boys gave his babe access, next thing she transferred 200k to her account and said it was for emergency. Emergency ke? She used it to buy weavon. I am not ready to be that statistic.

Also, this is not about hiding anything. I just believe privacy is important even in relationship. If she doesn't trust me without my password, then the problem is deeper. As one person said online,

Trust isn't based on having your partner's passwords – trust goes beyond passwords and accounts.

She should trust my word, not my transaction history.

What I think she should do

If she wants to see how I spend, we can sit down together once a month and go through expenses. But giving her the app access 24/7? That's a no for me. Nigerian relationships are hard enough without adding financial control issues. If she can't handle that, maybe she should find someone else to control.

Abeg, what do you guys think? Am I being unreasonable or is this a red flag?
