I've been married to my totally different wife for nearly 10 years and I am an insomniac that hates being alone so I go clubbing a lot, wheras clubbing doesn't bother her. I was agressive, she was calm, I wanted and already had lots of children, she had just one when I met her,she is Jewish, I'm a Catholic,I am ambitious and a bit ruthless, she prefers quality in the work she does rather than financial success etc etc etc we are very different people, but what binds us together is that essentially we share the same core values of fairness, how to bring kids up etc. All of the differences of belief etc and social goings on really don't matter as long as you are the same type of people in your deepest selves so I think an extrovert and an intorvert can get along very well.
