I think the point about infatuation is that (a) it involves a completely false, rose-tinted picture of the person concerned and (b) far from being short-lived it can go on for quite a while, long enough in fact for you to cohabit or marry before you realise how deluded you've been.
I guess on the whole I'm too level-headed a person to have been infatuated with anyone for long, but I was absurdly besotted with one particular woman for a year or two, despite all the evidence that she wasn't nearly as special (or compatible, or even available) as I thought.
Fortunately for me it was an entirely unreciprocated besotting, so it never got to the stage of living together or tying any legal knots, and I never faced the humiliating final stage of seeing my perfect partner turn into a mere mortal who just got on my nerves rather than inspiring me.
Even if I'm not prone to infatuation, I've often idealised someone to the extent that infatuation wasn't far away. I've exaggerated their virtues and overlooked their faults to a ridiculous degree, I suppose for the usual pathetic reason that I'm beguiled by their beauty and assume they must have a beautiful brain to match. Which of course absolutely doesn't follow.
I'm also easily taken in by confidence and poise, which I carelessly equate with exceptional wisdom. While in reality it may only mean they've always had it easy.
But at my advanced age I've met enough people with bird brains and feet of clay to make me look long and hard at anyone who comes trailing a saintly aura. The saintly aura might just be a cloud of cobwebs.
