song question from episode 11

About two thirds into episode 11, "The Benefit of Putting in the Work," Ben says to Sara that she has to decide if this guy Austin who she's dating is worth it--Austin is on anti-depressants and takes a long time to come when they have sex. Anyway, as Sara thinks about how great Austin is, a song plays with the following lyrics (it's a girl singing):

Tell me I belong
You are the sweetest thing to me
Say that I'm not wrong
You have the sweetest thing for me

Does anyone know what this song is? Thank you. :-)
