when love is too much - it's not love at all...
it is a lot of things (possessiveness, insecurities, undoings, etc) taking the appearance of love but not love itself.
if the person receiving your love can no longer breath because of your love, then you are not actually giving her love which is freedom but prison (a non-love)...
love creates happiness for the recepient - not sadness...
love, just like anything given in excess - kills (especially itself!)
