I can't remember who wrote this one (I think it was a Scottish band) but this another one that gets to me. In some ways, I have been there and certainly done the wine bit. The person I learned it from told me he had was going through a split up when he first heard the tune and it took him a while before he was able to sing it.

What Shall We Drink to Tonight?

Remember a time not so long ago?
You couldn't say goodbye now you can't say hello
So I'll pick up the glass and I'll pour me some wine
And say what shall we drink to tonight?

What shall we drink to tonight?
What shall we drink to tonight?
I'll drink to the lassie who should have been mine
That's what I'll drink to tonight

Now that your gone these things I recall
The way that you smiled, the best smile of all
So I'll pick up the glass and I'll pour me some wine
And say what shall we drink to tonight?

What shall we drink to tonight?
What shall we drink to tonight?
I'll drink till the landlady calls that it's time
That's what I'll drink to tonight

Now that I've heard that you've found someone new
It could have been me if it wasn't for you
So I'll pick up the glass and I'll pour me some wine
And say what shall we drink to tonight?

What shall we drink to tonight?
What shall we drink to tonight?
I'll drink till this bottle is empty and dry
That's what I'll drink to tonight

What shall we drink to tonight?
What shall we drink to tonight?
I'll drink to the lassie who should have been mine
That's what I'll drink to tonight
