Can you define what is love? (love between man and woman)

well for me attraction is important (I'm good looking so i expect the guy i'm with to be goodlooking too). There has to be a reason why you want to be with them thats the attachment part. And you need to have somtheing that keeps you togehter for example both of you like going to movies every friday or you both love going shopping, or you cook for him one morning and then he cook breakfast for you etc.. So i beleive your little equation or definition of love between a man and women is pretty accurate.
