Them (aka her):
You are amazing. You are the best.
You are annoying. You are a pest.
I love you more than anything ever.
I think that you're funny and clever.
But that's not enough for me.
You're too much, apparently.
Even though I "care" about you,
I'd leave you even when you're blue.
You're not worth the pain, the stress, even though "You're the best!"
