It's Harder Than It Looks
Psychology Today: Intimacy: The Art of Relationships
Definitely a worthwhile read... here's a brief excerpt from the intro:
"...most of what goes wrong in a relationship stems from hurt feelings. The disappointment couples experience is based on misunderstanding and misperception. We choose a partner hoping for a source of affection, love, and support, and, more than ever, a best friend. Finding such a partner is a wonderful and ecstatic experience--the stage of illusion in relationships, it has been called.
...there then sets in the state of disillusion. We somehow don't get all that we had hoped for. He didn't do it just right. She didn't welcome you home; she was too busy with something else; maybe she didn't even look up. But we don't have the skills to work out the disappointments that occur. The disappointments big and little then determine the future course of the relationship."
