In season 2 episode 9 'the ex factor' an instrumental song plays while Lindsey is in Marissa's bedroom?

In season 2 episode 9 'the ex factor' an instrumental song plays while Lindsey is in Marissa's bedroom and then at the end when Ryan goes to Alex's to apologise to Marissa. Does anyone know what the song is, tried to Shazam it but doesn't come up with anything? Thanks
