Under no circumstances should you ever put yourself in the position of giving or denying your spouse permission to go after something he or she wants, be it a thing, a personal goal, a certain amount of time or attention, or an emotional investment on your part. Negotiating the what (instead of the how and when) in marriage changes you from a partner into a parent, and it reduces your spouse from an adult to a child. Inevitably, this dynamic creates the kind of resentment that, if allowed to go unchecked, causes divorce.
