Confuse much!

I have trouble deciding on what should be my final judgment( how harsh).
My final decision about our relationship.
If i should end it now or prolong his suffering?
but i am in pain too.
Even if it hurts, but i strongly agree that guys get so insensitive to their partners as time goes by.
They are just good when they are still courting you.
Even you have sacrificed almost everything to and for him, but it doesn't matter.
although, he keeps on saying he is so sorry, but then again, damages have been already done.
I need a major reconstruction!
as what he have told me, SORRY is the deepest while PROMISE is the biggest word that we could say to each other.
And i am going to add on to that, GOODBYE is the hardest word for us.
