This is what Shakaar feels when Kira leaves him for Odo. Song mode 'Mr. Brightside', with a few modifications… I own nothing know matter how much I want to.

Cardies let us out of our cage
And we've been doing just fine
Gotta gotta be down
Because we want it all
It started out with a kiss
How did it end up like this
It was only a kiss, it was only a kiss
Now I'm falling asleep
And she's starting to nag
While I'm having a smoke
And she's packing her bags
Now she's going to bed
With some other man
And it's all in my head
But she's touching his chest
Now, he takes off her dress
Now, letting me go

Don't understand; it's killing me
I'm losing control
Jealousy, Prophets drowning in the sea
Becoming deaf through lullabies
I don't have an alibi
But it's just the price I pay
Prophets, they are calling me
Bajor, open up your eyes

Cause I'm Mr. Brightside

Cardies let us out of our cage
And we've been doing just fine
Gotta gotta be down
Because we want it all
It started out with a kiss
How did it end up like this
It was only a kiss, it was only a kiss
Now I'm falling asleep
And she's starting to nag
While I'm having a smoke
And she's packing her bags
Now she's going to bed
With some other man
An' it's all in my head

But she's touching his chest
Now, he takes off her dress
Now, letting me go

She really is; She's killing me
She's taking control
Jealousy, Prophets drowning in the sea
Becoming deaf through lullabies
I don't have an alibi
But it's just the price I pay
Prophets, they are calling me
Bajor, open up your eyes

'Cause I'm Mr. Brightside
