"all the things that could go wrong" lyrics

I'm at your door like I've already planned it
Just what I'll say when we know this is ending
You open the door and you take my hand
Nothing's according to plan
I'm trying to understand

If this is the happiest I've ever been
Why do I feel so afraid of it?
Holding your hand as we're walking along
I'm thinking about all the things that could go wrong
If you said "Forever" and nothing could change
Why can I see you walking away?
I try to believe this is where I belong
While I'm thinking about all the things that could go wrong

You came at a time when I needed to meet you
Just say we're all right and I'll try to believe you
But we sat on the lawn and you let out a tear
A realization of the same kind of fear
Wish I could help you understand

If this is the happiest I've ever been
Why do I feel so afraid of it?
Holding your hand as we're walking along
I'm thinking about all the things that could go wrong
If you said "Forever" and nothing could change
Why can I see you walking away?
I try to believe this is where I belong
While I'm thinking about all the things that could go wrong

If you said "Forever"
If you said "Forever"
