Here is a love song I heard just recently.  This is about commitment, growing old with a loved one.

I always believed that relationships involve investment - in time, effort, feelings including future.  I just want to delve into that thinking for now.  It is always nice to look forward but what if something happens along the way?  At least we got today - which we call the PRESENT - so let's grasp it while we still have the feeling.

I WANNA GROW OLD WITH YOU.

Another day 
Without your smile 
Another day just passes by 
But now I know 
How much it means 
For you to stay 
Right here with me 

The time we spent apart will make our love grow stronger 
But it hurt so bad I can't take it any longer 

I wanna grow old with you 
I wanna die lying in your arms 
I wanna grow old with you 
I wanna be looking in your eyes 
I wanna be there for you 
Sharing everything you do 
I wanna grow old with you 

A thousand miles between us now 
It causes me to wonder how 
Our love tonight remains so strong 
It makes our risk right all along 

The time we spent apart will make our love grow stronger 
But it hurt so bad I can't take it any longer 

I wanna grow old with you 
I wanna die lying in your arms 
I wanna grow old with you 
I wanna be looking in your eyes 
I wanna be there for you 
Sharing everything you do 
I wanna grow old with you 

Things can come and go I know but 
Baby I believe 
Something's burning strong between us 
Makes it clear to me 

I wanna grow old with you 
I wanna die lying in your arms 
I wanna grow old with you 
I wanna be looking in your eyes 
I wanna be there for you 
Sharing everything you do 
I wanna grow old with you
