Life and love are supposed to remain mysterious wonders. Believe anything you want.
I sure hope that won't be literally true in my universe, which is not to say there isn't any room for romantic obfuscation of reality.
Likewise, and despite all arguments to the contrary, beliefs are inherently irrational coping and comforting mechanisms (there's your 'benefit') generated by a brain lacking in understanding or means to deal with issues in a more active and fundamental way, but that doesn't mean there isn't room for that either. That is, as long as you remember what and where you are, and won't let beliefs dictate your options to the exclusion of everything else. But that's my 2¢...
