You are awakened to the cold reality that he is leaving; but your feelings for him have not changed.
Your top priority is to get him to love you again.
This emotional abandonment has left you helpless but not hopeless.
If you must give vent to your frustrations, do it in private.
Do not let others, especially your lover, glimpse your broken façade.
When your emotional outburst is complete, you begin to feel better and your mind becomes clear.
The best thing to do at this point is to keep out of touch.
If ever your path accidentally crossed, do not snub him.
Show him how unaffected you are.
Give him a beautiful smile and act naturally.
If you look nice, smell nice and act friendly, he will start to think about you and start to remember how happy you were together in the past.
You have started the ball rolling.
Never initiate any kind of communication.
In the meantime, focus interest on yourself.
Get the approval and support from your friends.
Do well in your study or work.
Once you get him out of your head, you can function better.
At the same time, your absence will make his heart grow fonder and he will regret rejecting the happiness you both shared.
This change of heart is the key to your problem.
Since he started the break-up, he will initiate the reconciliation.
Do not immediately jump into his arms.
Take your time so he will realize your worth.
Now, you have fulfilled your desire to get him to love you again.
