I find it amazing how often people will end up with a partner that is quite different from themselves. Those who study such things tell us not to be so terribly amazed. This is often the case. Extroverts marry introverts. Rational people marry emotional sorts to help them feel.
Emotional people marry rational sorts to help themselves think.
Those sorts of differences can lead to some struggles and sparks. But they also can lead to a much stronger marriage when those involved can acknowledge the differences, celebrate them, and build on the strengths of each other. I'm sure you won't be too terribly surprised to hear that things are not terribly different in the Church. But when it starts to come close to home it gets a lot more difficult. See, we human beings are creatures of habit.
