This song is more appropriate in light of certain recent events than I’d like. But it’s still the best song I know to describe particularly acrimonious splits.
When I’ve reached my limits, I have a tendency to just sever ties and walk away. It’s easier than trying to mend hurts or breaks.

But sometimes there is no fixing things. You say things that just spill out at the wrong time, to the wrong person and there’s no going back. No do overs. No resets.
But by itself, it’s still a beautiful song with its sparseness, its simplicity. “Leave,” he sings. Because you can’t bear to be near the person, you just want the person out of your sphere so you can attempt to rebuild, regroup and recover.

The best cover I’ve found is this rather slow and sweet rendition which starts off so quietly before the control breaks, and it just becomes an anguished, strangled cry.

The original by Glen:

I can’t wait forever is all that you said

Before you stood up

And you won’t disappoint me

I can do that myself

But I’m glad that you’ve come

Now if you don’t mind

Leave, leave,
Leave, leave,

Let go of my hand

You said what you have to now

Leave, leave…
