When one partner holds all the wild cards, the other partner just folds.
Mark held all the cards and still he believed his second wife should trust him. He made her sign a prenuptial agreement and then he managed their finances and determined her monthly allowance. Then seven years into their marriage, he set up a trust to provide for his kids but forced her to sign it without letting her read it first. This is not how you foster trust in a relationship. Treat each other like equal partners, shower one another with kindness and sacrifice. That is how you do it.
