once a cheater always a cheater? not so fast! I have a book that might change everything you know about love, sex, marriage, and dun dun dun cheating! Esther Perel hopefully isn't a stranger to you, i cover the gems of "that state of affairs" and even talk about the time my boyfriend cheated on me with multiple women while i was cooking for him. and yeah, one of the girls was my roommate.
