Found out today she's been paying off other debts (presumably loans/credit cards) before us.

Is it unreasonable to insist she sends us a full breakdown of her finances, including take-home pay, outgoings, savings, etc?
Yes, completely unreasonable. Makes sense to pay off the high interest loans first so she will be in a better posiition to pay you in the future. You can't control what she spends her money on after you agree the reduction.
