This is what I do. I ask myself, If they gave me everything, and I mean everything that I would want from them. Such as knowing everything about them and giving me all Affection, Attention, respect, Trust, any material things, and most importantly knowing all this. Would they still intrigue me? Or "make me tick" Thats how I would determine superficial attraction from the real deal.
Wether you believe in love or not, you have to believe in long term compatability. When you're not 100% sure what love is go with what you know.
Impossible is a word only to be found in the dictionary of fools.
