What kid grows up and thinks, "gee, I'm going to marry somebody and get pulled into arguments, then disrespect that person and treat them like they owe me something!"? For that reason, I think self-awareness should go along with respect and common sense (implies common understanding).
Soulmate? What they ^^^ said, although a "dull" rusty ice-pick might be more to my liking. It's a fallacy started wayyyyy back with Plato and the like. And the problem with falling in love, is you can fall right back out of it. Commitment has a lot more to do with a life partner and the love of your life.
Just my $.04 worth (adjusting for inflation)
