It is so obvious that she is so immature. She breaks off her year long relationship with Sam because he does not love her back. It is so not true love, but rather hero worshiping because he saved her/infatuation. She cannot demand that somebody love her. They either do or not.
I really wish CV would minimise the PDA (public display of affection) between IRA and SAM, it is so not appropriate. Well I dont appreciate watching it.
