Even on the most trivial decisions, never say, “Do whatever you want.” If she asks you which shoes you think look better on her, make a decision, and tell her. Don’t just say, “They’re both nice.” Say something like, “I’d like the red shoes, but what’s the most important to me is that you’re happy.” She is of course free to wear whatever she wants, but she is also the recipient of your masculine gift of decisiveness.
