Mystery called Love

Love is perhaps one of the biggest mystery in this world. It is most common and yet unexplained phenomena.
Just now, I read a forward giving message " don't look for people you love... Look for people who love you"
Love does not just mean the boy and girl love, includes family, friends also.
However the boy and girl love (the other combinations are also implied, so don't get offended if you belong to them) is the hot discussion everywhere (it always is, whole of Bollywood and Hollywood runs on it) and let's just continue with it.
Well, can you really predict that so and so will fall in love with so and so, impossible! isn't it?
Well, I am so stupid that I can not understand what exactly this love is what but at the same time I am not stupid enough to call physical attraction as love. However, if you are great fan of hollywood and bollywood movies it might prove to be very hard to argue against the fact that in many cases(well! I am just being diplomatic or rather politically correct) physical attraction is trigger to this so called love.
In most situations (which I have seen), it starts when the two characters of the story meet each other for some or the other reason and then start talking with each other and they first like each other's talk (my god! I just discovered the first road block in my love journey or rather why I don't have any girlfriend, I am very poor in conversational skills). And, then they start meeting each other often and realise that they like each other's presence (most often they get blinded and not able to see each other's annoying habits which afterwards becomes huge problem) and then they realise that they love each other. Now, the trick here is that what causes this realisation that I love her and things like that. Well, to be honest, I am clueless, do you know it?
I have one friend who exactly like me had opinions about love and used to ridicule things like love at first sight (Well, I ridicule it even today) and then hopelessly fell in love with a girl.
So, again what does it mean? Does it mean that when you get emotionally very close to someone, you have fallen in love?
Anyway, is there anything called true love, isn't it just a moment when we decide to commit ourselves emotionally, physically,.... to someone for life?
When the relationships break, was there any love between the two or love is just flexible enough :) to change over time?
I am not trying to give any answers, I don't know any.
Well, just when I thought I will finish this blog, I remembered one observation. There is one peculiar thing that people who go to some other country where similar people are much less, they normally fall in love or commit to marriage easier. In fact, the friend, I mentioned few paragraphs ago, fell in love with the girl in foreign country. So is the loneliness (or emptiness, which I use to term extreme loneliness) one of the factors here? Is it that when you are away from your family or people you love or you don't have anyone who loves you; you start looking for someone who will and when you see a possibility you fall in love?
I guess my thoughts are too random, but I guess that's the way they should be.
congratulations! if you are reading upto this very last line.
