Heartache. Real. True. Pain whether the loss is a death, end of a relationship.. Some things are difficult to overcome. Your life may go on, but you may never stop loving that person. And I don't stop loving YOU :(
The flip side of true love. Sadly, one day will likely come when one of you has only memories of your love. Remember to rejoice for the good times and that person you lost would want you to move on and still have happy times without them.
