Cool -- Gwen Stefani

It's hard to remember how it felt before Now I found the love of my life
Passes things, get more comfortable Everything is going right
And after all the obstacles It's good to see you now with someone else
And it's such a miracle that you and me are still good friends
After all that we've been through I know we're cool

We used to think it was impossible Now you call me by my new last name Memories seem like so long ago Time always kills the pain
Remember Harbor Boulevard The dreaming days where the mess was made Look how all the kids have grown, We have changed but we're still the same After all that we've been through
I know we're cool I know we're cool
 
And I'll be happy for you If you can be happy for me
Circles and triangles And now we're hanging out with your new girlfriend So far from where we've been  I know we're cool   (sing365)

Gwen and Tony dated for 8 years before breaking up because Tony needed "space." The song is about how both of them have moved on and how through the ups and downs, over the years, they've become really good friends. Gwen has found the "Love of her life," Gavin Rossdale, so now things are more comfortable with Tony and Gwen hanging out together (songfacts)
