Trying to Move on

I saw your face today
But I saw hers too
Your arm was around her
And her arm was around you

You guys were happy
And I won't interfere
Sometimes I just wish
She would disappear

When we were together
You were happy too
But now I have nothing
And now she has you

When you guys come around
I'll try to be strong
But really in my heart
I'm just trying to move on
