The thing about love is it makes you go mad, crazy, real crazy and makes u do unbelievable stuffs and how long will u stay mad depends on how much love you are receiving.
If the love received was once great and now it has diminished won't entirely matter to the lover as long as it was for legitimate reasons. The lover would still love based on the person who was and not who is right now.
But love is greedy , love is selfish; love would need its attention, love is possessive, love needs to be nurtured between two people and not with the involvement of others.
These all can happen when there would be proper communication between the two people. If one person is in love and he isn't receiving anything in return, he won't be able to stay in love forever, he would be in constant turmoil, he would be in a constant battle with his mind and his heart -- mind saying to move on , she has nothing for me but the heart constantly reminding about her smile, her giggle, her naughty behaviour that you only got to see, her care, every single thing about her gets rewinded through the memory lane -- and every single time the heart wins.
But how long?! How long will the heart win?! The heart will eventually crack and will start to fall apart and still he would love her with each broken piece, with each piece representing her smile or care or anything about her.
But the colours of her memories will soon start to fade away, his heart would slowly heal, his heart would slowly stop grieving, his heart would slowly try to put together but this time he won't be having that mad, crazy heart who loved so freely. Instead it would go numb, incapable of loving another no matter how hard he tries and no matter how much he receives.
The heart once at peace is a heart no more capable of loving like before. He might want to say a lot of words, he might want to express it a lot but words won't come out of his mouth, instead tears would roll down his eyes!!
