I'm not disclosing savings to my fiancee
Why keep it from her?
she doesn't deserve it. She shouldn't worry about money especially when I'm not spending money on anything else.
You should not hide your finances from your wife. Couples mostly break up over money problems and you should get at that before it starts.
I'm going to be the worst husband a woman could have.
Keeping secrets and you don't want to share why would you even get married? You should be able to trust each other, you know you would be liable for her debts if you do get married right?
