Being a successful couple was learning what you were willing to compromise on, and what you weren't; learning when to stand your ground, and when to give it up; what was truly important enough to fight over, and what was just you being pissy. You learned each other's hot buttons, the places that hurt, or angered, when you pressed them. Love makes you learn where all the pitfalls are, and how to avoid them, or how to set them off.
