It seems like being in love with someone is only temporarily until the love goes away. That happens with me all the time, and it seems to happen to most people. People seem to always be falling in love with someone, and then the love stops, and they break up or get a divorce with that person. A lot of times after a couple break up or get a divorce, that used to be couple start hating each other.
It seems like the couples that don't break up or get a divorce and are still together throughout the rest of their lifetime don't stay together because they are in love (in which most likely they aren't), but because they benefit each other. A lot of the old couples I've seen don't seem to love each other at all.
A lot of couples get married because they benefit each other instead of being in love with each other. In fact, back in the old days, most people got married because of the benefits and not because of love.
In my opinion, I think platonic love is better than romantic love is, since it's 100 times more likely to last throughout a whole lifetime instead of the romantic type of love.
