"Happier" lyrics

I've noticed a difference
In the way you hold your head
Think we're getting better
Put all these fights to bed

I've found all my trust, picked it up off the ground
Dusted it off, and forgot all about
The stranger who took something the belonged to me
A night with my love, but I let it be

Your smile is going further, your eyes are looking bright
Darling, you look happier, but something isn't right
It hits me in the stomach and wraps my heart up tight
Darling, you look happier, 'cause you've been with her tonight

I know I seem crazy
Like part of my mind has gone
I've always loved seeing you happy
Even though the reason's so wrong

It hits me in waves, I'm falling, I break
I thought we were safe, I love to forget

Your smile is going further, your eyes are looking bright
Darling, you look happier, but something isn't right
It hits me in the stomach and wraps my heart up tight
Darling, you look happier, 'cause you've been with her tonight

And I wish I didn't know, 'cause ignorance is bliss
And I wouldn't think about all the phonecalls that you missed
What you were really doing, who's filling up your heart
And breaking mine?

Your smile is going further, your eyes are looking bright
Darling, you look happier, but something isn't right
It hits me in the stomach and wraps my heart up tight
Darling, you look happier, 'cause you've been with her tonight
