It strikes the romantic myth straight in the heart, yes. That there's one person designed for you, by God or Nature or Ms Destiny, and an unspecified number of little winged guys arranging everything for you to meet and shooting those little arrows when you do. Buying into the myth is what makes poor fools (like me 
) stick with a rubbish partner, because, see, all those things that had to be just right for us to meet, you'd be betraying the universe to split with him. Plus that feeling that you've failed - you've let all the little winged fellows down - if you can't keep a relationship going even when the other party is knocking you about, sleeping around, or just not really interested. It was "meant to be", so why can't I keep it going?
What about the reverse, where Destiny is sending anti-Cupids to push you away from someone you shouldn't be with? No, in that case Love is supposed to Conquer All, and you may die horribly but it's ok as long as you do it Together. Very very silly isn't it! Missing the whole point of getting together with the opposite sex, too, as you can't procreate or even provide mutual support when you're dead.
Fortunately Romance does exist, shorn of its mythical trappings, and it's a lovely thing providing it's mutual and has practicality to back it up. It's not supernatural, it's entirely natural, and that's what makes it good, because it's part of being a living, feeling human being. It isn't some external force; it's in you. The good thing about that is, if one relationship goes tits-up despite what effort you put into it, Romance is still a part of who you are and you can find it again with somebody else.
