Prep for the meeting as you would a job interview: Dig around a little and get to know the parents before you even get there. “Get a sense of the family culture,” suggests Sara Sharnoff, a dating consultant in Boston. “Ask your guy: Do they shake hands or hug? Should I address them as ‘Mr. and Mrs.’ or by their first names?” Let your guy fill you in on their likes and dislikes so you can prep a few ice-breakers (and avoid touchy topics). And if you’re planning an extended visit, discuss your parameters with him first. “It’s okay to request that he not leave you alone with them,” says Miami-based therapist Lisa Paz.
