@Lash,
Love does not need to be returned or even appreciated.
I put money into a charity, I do it all the time, I don't know where it goes other than to (I hope) some unfortunate person I do not even know at all. No conditions, no stings and no expectations in return. Other than the charity honor my charity by seeing someone is helped. I am a man but I would still donate money to planned parenthood so that some woman who is raped can get an abortion. That is love too.
Conditional love is NOT love, it is a wage, blackmail, payment. Real love is not for sale... (maybe sex though)
If you do this ( blah, blah blah), then I will love you... REAL love is there even in our darkest hour.
Often we are loved by someone and it may take a while (even years) before we realize the enormous heart behind it, and this moves us to grow and become better human beings.
