Some people do everything and gave everything for the sake of it.. for what just to be happy? and leave the other one miserable? Sometimes you need to follow your heart than your mind. And some don’t because they say that that is the reason why your mind is higher than your heart.
Sometimes loneliness gives the person strength to be strong and to be able to move on. But some this is the reason why other people do things like revenge just to say they moved on. But whatever their reason they just need to learned from it, be strong, moved on and start again.
