Buffy the Vampire Slayer, Season 6

Tara:
Do you think I'm stupid? I know you used that spell on me.

Willow:
Tara, I'm sorry, I-

Tara:
Don't! Just... don't. [shakes head.] There's nothing you can say.

Willow:
Tara, I didn't mean to-

Tara:
To what? Violate my mind like that? How could you, Willow? How could you after what Glory did to me?

Willow:
Violate you? I... I-I didn't ... mean anything like that, I-I, I just wanted us not to fight any more. I love you.

Tara:
If you don't wanna fight, you don't fight. You don't use magic to make a fight disappear.

Willow:
But I-I just wanted to make things better. Better for us.

Tara:
But you don't get to decide what is better for us, Will. We're in a relationship, we are supposed to decide together.

Willow:
Okay. I'm ... I realize I, I did it wrong.

Tara:
You did it the way you're doing everything. When things get rough, you... you don't even consider the options. You just ... you just do a spell. It's not good for you, Willow. And it's not what magic is for.

Willow:
[apprehensive.] But I... I just wanna help people.

Tara:
Maybe that's how it started, but ... you're helping yourself now, fixing things to your liking. Including me.

Willow:
Tara, no!

[Tara looks away.]

Tara:
I don't think this is gonna work.

Willow:
Hey. It is, i-it's working. [Tara just looks at her, then looks down.] Tara, please. I need you, baby. I need you. I don't need magic, I-I don't, I ... let me prove it to you, okay? I, I will go a month without doing any magic. I won't do a single spell. I swear.

[Tara looks back at her.]

Tara:
Go a week.
