"We're always going to be newlyweds."

Last July Katie Holmes said she and Tom Cruise would
always be in the honeymoon phase.

This July Heidi Klum said of her marriage to Seal: "We're always going to be newlyweds. I really hope so. Things are good."

The feeling that love will last forever seems universal to the "in love" experience.

I don't know how I feel about you

I don't know how I feel about you

There is no one way.
I feel so many things, and all at once.

Happy…
but kind of scared too.
Excited.
Calm.
Lost.
Found.
I feel safe in a way that I've never known, but in danger too.

This thing between us, whatever it is, it's stronger than me.
Being with you is stronger than me alone.
That's new to me.

Dean Cain got to speak those words in the "Ordinary People" episode of Lois&Clark
written by Eugenie Ross-Leming and Brad Buckner, Season 3, Episode 2

"I only want to be with you"

Dusty Springfield sang:

I don't know what it is that makes me love you so
I only know I never wanna let you go
'Cause you started something, can't you see
That ever since we met you've had a hold on me
It happens to be true, I only want to be with you.

It doesn't matter where you go or what you do
I wanna spend each moment of the day with you
Oh look what has happened with just one kiss
I never knew that I could be in love like this
It's crazy but it's true, I only want to be with you.

    You stopped and you smiled at me and asked if I cared to dance
          I fell into your open arms; I didn't stand a chance

Now listen honey—
I just wanna be beside you everywhere
As long as we're together, honey, I don't care
'Cause you've started something, can't you see
That ever since we met you've had a hold on me
No matter what you do, I only want to be with you.
