Looking for book in which the first scene is the hero tells the heroine he needs to see other people,but she cant or wont move out and seems to think her staying will make hime change his mind. Somehow she leaves and goes to live with her sister who used to date the brother who is a football star who the sister was dumped by so the sister turned to having random sexual encounters. Heroine starts to fall for one of the sexually free neighbors of her sister but still gets pulled back to the douche bag boyfriend in the end. She ends up living with a neighbor who lives across the street from the hero. The hero also apparently brought a female whore home to sleep with and the heroine heard them. Also I think the hero's father was also involved with the whorish female wo came to the house...
