The Legend of Korra, Book Two: Spirits

Bolin:
Mako! I'm so happy to see you!

Mako:
Uh, you all right, bro?

Bolin:
No! No, I'm not all right! I can't take anymore. Listen, I don't want to live in icy bliss with Eska! [sobbing] Don't make me! Oh, please, please don't make me.

Mako:
Uh, hey, if you're that unhappy, just break up with her.

Bolin:
Break up with her? You can do that?

Mako:
Yeah. Guys do it all the time.

Bolin:
How?

Mako:
Just tell her you're not that into her anymore.

Bolin:
Oh, no, no, I don't think she'd like that.

Mako:
Ending a relationship is kind of like pulling off a bloodsucking leech. You just gotta rip it off and get it over with. You'll feel a lot better afterwards. Trust me.

Bolin:
Thanks, Mako. I'm lucky you're so good at breaking girls' hearts. [laughs] Korra better watch out.
