Dear Prudence: The "Sunk Cost" Edition

Writer and commentator Lindy West joins Prudence to encourage Thelma-and-Louise-style road trips for jilted lovers and discourage kicking people out of wedding parties. First up in your letters: My boyfriend period shames me. Help! My fiancé has been postponing our marriage for five years – what should I do? Should I tell my sister-in-law that her kids’ grandpa is a convicted sex offender? And finally: I’m a lesbian, but I want to stay in my heterosexual marriage to preserve my family. Is that wrong?
