This has to be one of the best of that specification: “You Can’t Take it with You When You Go,” by Rhonda Vincent and the Rage. Not too needy, not too tough: You can change your mind, but it’s a limited-time offer.

Watch where you’re standin’
When you close that door
‘Cause if you’re on the wrong side
It won’t open any more.
Be sure before you leave me
That it’s the only way
Take off your coat and think about
What I’m about to say.

(Chorus:)

I gave you my soul, completely
You’ve got my dreams;
You’ve got everything that I’ll need if you leave me alone.
I’ll give you my love
For the rest of my life
But I want to make sure you know:
You can’t take it with you when you go.

I hear what you’re saying
But I don’t believe it’s you
Tellin’ me that it’s all over
After all that we’ve been through.
If you’ve found a new love
Then just tell me so
And I’ll make it easy
So she’ll never know.

Chorus
