Personally I think being in love is something that happens only once, perhaps twice in a lifetime. To some it may not happen at all. I think it's the most intense emotion you can feel, and once you've truly fallen in love you will always be partial to that person.
Or maybe I'm just too emotional xD
But really, it pisses me off to the extreme when silly young couples go on about being in love and shite. Sure, there's a very slim possibility, but 99.9999% of the time it's a load of shit. And if they really experienced this emotion they wouldn't be throwing it around like candy on halloween, now, would they? :|
Got to say I've loved people, but never near close to being in love.
