Musician Adam Levine went on tour the summer before he wed Behati Prinsloo in 2014, but his band Maroon 5 didn't have a new album to promote. Nope, Levine had something else planned before he wed Prinsloo. He embarked on an "ex apology tour" – an odd trend to sweep the dating world as of late. Levine has a reputation for being a bit of a player, so he seemed to feel compelled to wipe his dating slate and his conscience clean before tying the knot. So he contacted a few ex-girlfriends, including Nina Agdal, who he infamously dumped by ignoring her. He texted her the news of his impending nuptials not long afterward. So is contacting your ex (or exes) out of the blue to apologize for your past transgressions – and deliver the news that you'll be married soon – a good idea? The consensus among therapists and those who have received such passive-aggressive apologies is no.
