When Jackie confronted Kevin about the call, he told her that he’d developed a secret spending habit because he was depressed. He promised he would seek professional help and assured her that all his bad behavior was the result of a chemical imbalance, which ran in his family.

After Kevin’s sixth therapy session, he’d come home in a rush, explained to Jackie that she was an enabler, and told her that he needed to move out for the sake of his own mental health. He promised to make payments on the card after he left, but he never did. He’d never even bothered having his mail forwarded. Jackie had taken responsibility for the rest of the bill without trying to contact him. She’d rationalized that she deserved to pay the price of overlooking the one crime she was trained to catch.

A year after the breakup, Jackie was more reserved and cynical than she’d ever been, according to Bee, who delivered Jackie’s tale to Hannah and the other bridesmaids at the hotel bar as if it were a haunted mystery. She whispered dramatically, her eyes wide. Hannah imagined Bee holding a flashlight under her chin.

Bee explained that when she asked Jackie to be a bridesmaid, her old friend accepted, but only after a long pause. Bee admitted that she often wondered whether the credit card and cheating disaster had left Jackie incapable of celebrating anyone else’s happiness.

“Maybe it just takes longer than a few months to get over that kind of loss and betrayal,” Hannah had snapped defensively in Bee’s direction after hearing Jackie’s sad tale at the hotel bar. “Being left without warning…It can ruin you,” Hannah continued, perhaps revealing too much about herself to Bee’s other bridesmaids, who were all married or about to be.

Hannah had imagined that she and Jackie would cling to each other during the bachelorette weekend and the Annapolis wedding. They’d be the only New Yorkers and single women in the pack. But it was clear after just a few hours in Atlantic City that Jackie wanted no part of Hannah’s camaraderie and that she had little interest in bridesmaid duties in general. Beyond that, Jackie already had a new boyfriend. When the fraud detector finally joined the other women at the hotel bar, she explained that she was dating someone new—an ear, nose, and throat doctor named Will. He’d be her date to the wedding. When Bee asked excitedly if it was serious, Jackie just shrugged.

It was hours after the bachelorette party dinner, when Bee was fall-down drunk at a place called the Smile Club and the still-energetic Dawn demanded that the group stay out for just one more hour, that Hannah looked to Jackie for support, a voice of reason to lead the group back to the hotel so the drooling bride could vomit and get some sleep.

But before Hannah could solicit Jackie’s second opinion so they could defy Dawn as a twosome, the fraud detector announced that she had a headache and would be heading back to the hotel room early. “But you guys,” she said, not making eye contact with Hannah, who stared at her in disbelief, “you stay out and have a good time.”
