MOST OF THE LOVE STORIES END because:
Your forget to tell each other everyday how much do you care for each other.
You take them as granted and stop giving time.
You start behaving formal after few days as if it is just a formality to update relationship.
You stop sharing things.
You stop behaving new and fresh like you did before.
One the initial days of relationship, you are possessive, determinant and opposite caring, you show and concern about their likes and dislikes, talk hours on phone and get bore soon so STOP TALKING SO MUCH IN PHONE ALL THE TIME, I GET IRRITATED WHEN PEOPLE AROUND ME DO NOT GIVE ME ATTENTION FOR THAT . Get a life you committed couples and feel the Fresh Air around
