Reading self-help books is a great idea; The Five Languages of Love (or something like that) is neat, as it talks about the different ways people show and feel loved; if you have a woman who feels most loved (and shows her love) through sweet words, but her partner shows and feels love through touch, you get conflict.
Then there are big life things- A wants a baby, B does not. A wants to move to a new city, B wants to move to the country. A wants a puppy, B wants a kitten.
Relationships are *rife* with conflict, from the tiniest little things (A likes the toilet paper to go over the roll, B likes it to come from under) to huge, monumental things (A wants to undergo sex reassignment surgery, B is not attracted to A's desired sex; A wants to sleep with other people, B doesn't want an open relationship, etc etc etc.)
