This is how I think it's played. I hope it's correct.
For the walkdown bit I suggest that you play an open A-chord using one finger so
that you can hit the G# note on the bass e-string in the A/G# chord
[A]Nothing like a memory to [F#M]open up a broken [C#M]heart
[G]Its been years but i look at you [F#M]now and we?re torn [E]apart
[A]Nothing like a face to [F#M]take you back to the t[C#M]ime
[G]When it was you and i against the[F#M] world just you and [E]i
[D]And i wish it hadn?t happened to u[E]s
[A]You fell in [A/G#]love with that [F#M]girl
[D]And i wish it hadn?t happened to u[E]s
[A]You fell in [A/G#]love with that [F#M]girl
[D]And i wish it wasn?t tr[E]ue
[A]But all you cared a[A/G#]bout was the g[F#M]irl
[G] [F#M] [E]
Nothing like a lover to set you up for a fall
You?re feeling you?re ready to die like you lost it all
Nothing like you and i in that place in time
And it?s so hard letting you go ?cause you?re still on my mind
And i wish it hadn?t happened
But you fell in love with that girl
I wish it never happened to us
You fell in love with that girl
And i wish it wasn?t true
But all you cared about was the girl
