Why did you have to leave

Could you give me a reason why
just thinking about this makes me want to cry
what did i do wrong to deserve this
the love we had is what i miss
i never believe that you would just let go
my love for you wants to grow
loving me was the best feeling i had ever had
but now that you are gone... i feel so sad
i can't breathe without you
so come back to me baby boo
answer me this on question
and tell me all your confession
answer me on Christmas eve
why did you have to leave
