This is the same dilemma with : "what comes first : chicken or egg?". As I watched so many couples have problems in their relationship coz one of them's acting really nuts, I often wonder, why do people tolerate their couple's weaknesses.

Like I once knew this girl whom, I think, really has many bad traits and if I positioned myself as a guy, I won't be interested in her at all. But turns out she got a boyfriend eventually and this guy always complains about her "bad traits". They lasted for a few months though.

So I found this annoying idea, which comes first in love : you love someone AND THEN like everything about him/her -or- do you like everything about him/her AND THEN you fall in love with that person?

I personally think it's the second choice, coz if it's the first, then the question  would certainly add up : what make someone fall in love? Is it just physical? Or is there more mystical way to explain the chemistry?
