Let her handle things on her own.

You take a step back to a more friend-like position. You acknowledge Tyler and Courtney smiles towards him. She looks over to you and it looks like she wants some space.

You leave her to break up with her and head for the kitchen. You smile at Carly as you pass and enter the kitchen. To your surprise you notice that all the girls in there are attractive. You see a girl who looks part Latina and part Caucasian with shoulder length styled black hair, a toned looking body with respectable tits. Hmm never met her before you think...

There is another girl in the corner who looks shy and is playing around on her iPhone listening to music, being a little anti-social. She's got black hair too, but a pale complexion but a pretty small chest. You realize she's just a little emo, but still think she's pretty cute.

The last girl that catches your eye you admire with a bit of familiarity and then as she turns you realize she's your ex. A girl you started to go out with but never actually let anything happen. you felt that she just sort of dragged you along for her own amusement.

You slip past the first girl and grab something to drink. You probably have plenty of time before Courtney and Tyler finish breaking up.
