Whether it's the big things or the little things, your man is likely to sacrifice his own happiness in favor of yours. You both love sitting by the window on bus journeys, but he'll let you have the seat every time you're travelling together. He would really rather drive to work, but he'd rather give up the car so you can drive it to your work instead.
When it comes to more serious things, he doesn't disappoint. If you want to move house, but he's quite content in your current living arrangement, he'll probably agree to it if he thinks it will make you happy. If he wants a family but you'd rather wait, he'll patiently agree. If you want your elderly parents to move in with you, he might not love the idea, but he'll definitely say yes.
