Psychotherapist Amira Martin knew that it made sense to move slowly when starting a new relationship, but after a whirlwind romance, she married a man she’d known for less than a year. After all, the courtship had been perfect—indeed, the man himself appeared perfect—and however improbable, Martin believed that she had found her soul mate.

She hadn’t.

Amira Martin spoke with Ms. about her marriage, its dissolution, and what she learned from it.
