LW's fiance put his thumb on the scale by wrongly adding the engagement ring value to the tally. That's neither trust nor respect, which are both needed for a healthy marriage. If he's willing to do that, he'll be paranoid about every penny LW spends going forward.

Arguments about finances before marriage are a big predictor of future divorce, and this one's a doozy. LW, call in Whole Man Disposal now. If he's been sending out feelers on a pre-nup, also dump him.
