The love of convenience

In my interactions with people over the last few months, I have noticed a particular trait in some settled-in-career/comfortable-with-themselves/available single guys which led me to wonder whether it is a trend or just a mistaken representation.
People are "looking for love". They get offended when questioned on their intentions on looking for just physical pleasure. They have a list of a thousand characteristics that they are looking for in the boyfriend-to-be, a mental picture framed in gold and hung for quite some time now, so much so that they aren't easily available to recognize it themselves. They treat each new guy that comes across nicely and everything, seemingly very careful and considerate not to hurt the other person by turning him down, all the while fulfilling their own need of momentary companionship i.e. a hand to hold and a head resting peacefully on their chests. Conveniently failing to realise that the other person is a mere unprepared human, not as mature as they are, the poor soul suddenly finds himself in love with all the friendly care showered by these benevolent creatures. They find an emotional anchor, and suddenly, much to their surprise, the anchor refuses to hold. Things are told to them - It was never meant to be, how could you think of us like that, there is no wavelength match, there wasn't anything physical between us anyway na... and so on.
Then these people just move on to another temporary companion to drink, throw party, watch tv, lay down (even share some "weak moments" with).... but mind you, all the time looking for that "love of their life"... spending the present with the love of convenience.
