The Perfect Combination

What makes of a perfect combination?
Is there really such a thing? I sometimes wonder why a couple lasts very long, is it because of compatibility? They said a perfect pair is about complimenting each other, for instance the woman’s weakness should be the man’s strength and vice versa. That is where “dating” comes in. Men and women go out on dates because they simply want to study their options & find out who they think and find very complimenting to their personality. Of course we should enjoy “dating” and make it less stressful. If a person forced himself to another though obviously they don’t gel in, one get disappointed & the other simply moves on. A person can't forced somebody to change just to be able to fill their standards because eventually the true identity will come out. You can only say you are a perfect combination when you accept each other's faults, beliefs, ideas, and make compromise with each others individuality.
