You know why some do not just move on? Its the time it took that got them there. The wrinkles in the eyes from all the laughs and worries, those little memories never go away. The fear of opening up and being rejected. Love not reciprocated. You expose yourself to the unknown in hopes its a goodheaeted place where your best interest is taken to heart. Its the effort, the pain, the happiness that got them there. No one wants to redo that. Others are lucky enough to not have experienced that.
