If you run into your ex-husband or ex-wife while out on a date, don’t cause a scene. There is no reason to draw attention to yourself. You should also not make a big deal out of it in front of your new partner as it gives him or her a bad impression. Instead, if your former spouse approaches you, be polite, and introduce them to the person you’re currently seeing. If they decide to behave impolitely, your date will see their true character without any assistance from you. If your ex acts courteous, quickly excuse yourselves and find a seat somewhere. That way, the awkwardness of the moment has time to dissipate before the meal is served or the movie begins.
