You know what, I don't like people's general attitude in this thread. :/
Sure it's true that at that age, you oftentimes don't know what love implies.
But to all of you naysayers, I say it is foolish to say that teenagers are incapable of true love. Love is love, and we are born with the ability to love, as young children, to love our parents and family.
Love is not something that I believe is defined by what society thinks of it. True love will make you do anything for a person...but sometimes fate gets in the way of true love.
You can have a true love and lose it by sheer circumstance, even if you take no risks whatsoever in regards to your partner's feelings, very easily.
As a society, we have this silly idea that love cannot be broken, when in fact, it's the most brittle and fragile of emotions when compared to others. You don't even have to hurt your partner's feelings to lose them, anyone could say anything and they'd begin to doubt something, even if you've been the perfect partner.
It's even possible for someone to mature out of a relationship at that age, and it's even quite common!
But even with all those odds against you...I say it's never a waste. You cannot rebrand it or call it something else, because both sides are novices, IT IS LOVE!
You are right; love is love. Who are we to judge and say something isn't love when love is different for everyone?
