Help me understand

Once in a lifetime
You'll open up your heart
Maybe once in your lifetime
You'll swear to never be apart
You think your love's on solid ground
Then out of the blue, it all comes tumblin' down

Who's gonna hold me tonight
When I'm feeling lonely
Who's gonna show me the light
'Cause I need to know
With all the things we've got
How can love just stop
Tell Me
Somebody help me understand

And my picture in your locket
What will you do with it now
All our friends and all our memories
Tell me how we sort them out
What's yours is yours
What's mine is mine
Is that all that's left
After all this time

Who's gonna hold me tonight
When I'm feeling lonely
Who's gonna show me the light
'Cause I need to know
With all the things we've got
How can love just stop
Tell Me
Somebody help me understand

Why I'm not part of your plan
And you don't need me anymore
Make me understand
Why I still wanna be where you are
Even though I know in my heart
That you don't love me anymore

Who's gonna hold me tonight
When I'm feeling lonely
Who's gonna show me the light
'Cause I need to know
With all the things we've got
How can love just stop
Tell Me
Somebody help me understand
