I do

I wanted to tell you
I still wanna be with you
I still want to accompany you for the rest of your life
I still want to by your side when you need someone to rely on
I still want to give you a smile to let you know I'm happy to be with you

but..

Am i still have chance?

Everytime i close my eyes
I can feel the pain in my heart
I don't know how long this will last for...
1 month?
3 months?
1 year?
or for the rest of my life?

Teach me what to do?
