Moment of loving and letting go

At the moment I see you smile
I've tried to keep my tears and say Goodbye
But every time i keep it inside
The pain will never go and subside

What should i suppose to do
If you say that i should let you go
I'm trying to ease the pain
That could put me insane

But my love for you will never die
Even i keep it telling with a lie
Just to see it, that you will be happy
Spending your time and love with somebody...
