Pain has become a constant for you that it is almost a comfort, it is a normal part of your life and has become apart of who you are.
Your days are spent caught between the motions of trying to find his love again and then trying to let it go. You feel stuck because you never truly make a decision.
I love the metaphor of the aching flower. Beautiful! Like this aching flower that has waited so long for it's last raindrop, you are waiting for the day when you will shed the last tear you will ever shed over them.
