Even those who have never loved have broken hearts..because they have never known love..the baby thing might be true. I think you learn to love stronger from heartbreak though...
i'm over 12 and have never had my heart broken...yet! probably because i had a male mentality of not letting myself fall in love or care about anyone too much, to stop myself from getting hurt. worked in the long run, but it turns out guys don't respond well to a lack of feeling haha
as far as heart broken by a lover nope i havent because i already knew it wouldnt last no one sticks around long when they see your problems up close and personal but my heart breaks everytime i hear someone died or just knowing people go without what they need sometimes or when someone gets bullied
my heart has never been broken :)
