How can i remember to forget

So I guess it's over, there's nothing left to say.
Take the ring off my finger and just call it a day.
Thought we had forever, but that was yesterday.
You're such a liar, wish I saw it on your face.
But you did it so well,
Can somebody just tell me how..?
How can I remember to forget?
When my heart just won't let me.
Make myself un-love you, tell me that it's not true.
I know all the reasons, but I just can't believe them,
and pretend we never met.
How can I remember to forget?
Wish that I could hate you, so I could
let you go. Wish I never met, the
one I want the most.
I could fill an ocean, with all the tears I've cried.
Tell me you were joking, just a dream I had last night.
But I'm wide awake and,
I want you so much right now.
How can I remember to forget
these emotions and all the plans we made?
Like we never happened, make my heart unbreak.
I know we're clearly over but I just don't know how..
How can I remember to forget?
When my heart just won't let me.
Make myself un-love you, tell me that it's not true.
I know all the reasons but I just can't believe them..
And pretend we never met.
How can I remember to forget?
Forget..
Oh.
Oh.
