I feel for what you went through but trying to equate having a need for a secret bank account hidden from your spouse to an uncle stealing funds from a minor is ingenious at best and absolutely laughable at best. There is obviously a difference between the two and if you don't realize that, I assume you must be a little too young to even weigh in. If you feel that unless you have a secret stash of cash you're in physical danger from your spouse then DO NOT MARRY THAT PERSON. it's not that complicated. Marriage isn't a joke or something to lightly go into. It's like saying "I don't trust you enough to not cheat on me so I'm going to keep a side man/woman on the side just in case. What? You don't like that?? That is a chillingly selfish betrayal of trust how dare you!" Just don't get married and merge accounts until you trust the person it's not that complicated, if you don't trust them enough for that, don't get married, simple as.
