you're right; such a claim would be dumb. fortunately that's not at all what I'm saying. what i'm pointing out is that
this scenario:
lasts for a few months; possibly a couple of years. biology is kicking in, the homorones are on drive, and everything is pink fluffy bunny rabbits, sunshine kittens, and rainbow smiles. but is that "falling in love", "falling in lust" or "falling into infatuation"?
then that goes away. in our self-obsessed culture this is called "falling out of love" though of course it is nothing of the kind. it is having the honeymoon period subside, the slow realization that infatuation does not last. you get bored, you don't know why the mystery, the adventure, the 'love of your love' (for do lovers ever really talk about much else for too long without mentioning it?) has dissappeared. plenty of folks, because the "falling in love" was so easy, assume that they will just stick it out, and wait for "love to come back". many break after realizing that it won't "just come back". and there is a reason that it won't - because Love ultimately is a choice. you decide you are going to love this person, you sit down and look at this man/woman and realize that they really piss you off. they have flaws you don't like. you have different interests. you realize all this deep communication you thought you had was just both of you
wanted it to be true, not necessarily because it was true itself. whatever that zing, that desire
for the love was, "it" just hasn't been "there", and you decide that you made a commitment, and you're going to continue to build a life together with them.
in previous generations, this was largely taken for granted. nowadays, we're a bit more me-focused. demanders of instant gratification, "falling in love" is supposed to be like in the movies - we meet, there is some initial attraction, perhaps a slight (but easily overcome) conflict, followed by a montage of how we are now perfectly happy for ever and ever and ever

and when that fails we simply declare that we have "fallen out of love" oh well no harm done, certainly not anyone's
fault; could happen to anybody, really... because we're not realizing that inaction, too, is a choice.
yes. i sat down and made the choice to continue to love this woman, even in the times when i didn't want to, even when i didn't feel "it" or like it. and we are all the better and more secure together for it, for each of us knows that we are not held hostage to random wind-blowing, horomone levels, conflict from distressing life-events, or proximity to pink bunnies. both of us have chosen each other, made a conscious decision to love and work on loving each other.
