The most common promise made in a person's wedding vow to their spouse is that they'll love them for better or for worse. This promise is also the most tested in any marriage, particularly around lunch time. When you're starving and you don't realize it, your spouse is the first to know that something is off. He knows that we'll be reaching the "for worse" times in about 25 minutes if we don't get this woman some food. It's not your fault that you're sometimes crazy, but at least you have a person bound to you who is pretty much legally obligated to deal with your mood swings. Your spouse is also the most equipped to deal with these moments— it's like they can see them coming like an earthquake on a seismograph. Hubby is ready to evacuate the premises. Regardless, he probably also cherishes your good moods as much as he's prepared to deal with your bad moments, that's what marriage is all about.
