why do we fall in love with person we tend to hate ? So, in love it becomes a habit to be with and have each other's company and when this fails to occur, there is a deep down feeling of discomfort in oneself. Now, if u hate somebody so much that u always keep of thinking about him (like thinking of his pranks and cursing him all the day long), it sooner or later becomes a habit and the person whom u used to hate so much got a permanent living-place in ur mind. U always keep thinking of him/her. Sometimes, if the cause of hatred was a silly one, one ultimately realizes it, and the hatred then disappears but the habit still remains.Thus, the habit without hatred makes u want that person beside u (as u hv become habituated), which actually becomes love. More importantly, true love does not lie in the fact, that one loves the other for only his/her good qualities but in true love one actually begins to like even the faults and the bad qualities of the other.
