As long as the basic relationship requirements are met by both people, and there is a mutual respect for each other's differences... then yes opposites definitely can make it work!

I don't want to date someone the absolute opposite of me, that is a recipe for disaster. However, you need someone who BALANCES YOU OUT. You don't want people who are exactly like you, especially who has all of the same flaws as you. If you have two forgetful people, you're boned. So it's good to find someone who has traits similar to you but someone who balances the things you lack or to have someone with their own interests separate from you.
