Like I said, remove him from your handphone and MSN. Change your
number if you have to.
Burn all his photos and love letters and give all the gifts he gave
you to charity.
And last of all, if he ever asks you to return to him, do not do so
unless you're absolutely sure that you can make the relationship
work. If you're even 1% hesistant, don't bother going back to him,
or you're going to end up even more hurt than ever.
