In the summer of 2012, Marlon and Laurel became a couple after a year of love and attraction between them. This caused major problems for Laurel's marriage to Ashley, who started abusing his father Sandy as a result of the stress of trying to make the marriage work. When Laurel discovered this, it signaled the final blow for the couple. With Marlon, Laurel is now maintaining a friendship with Ashley. Marlon let Ashley move in with him after he had nowhere else to go, having moved out of the marital home, where Laurel remained with Sandy and the kids. The children struggled to cope following the recent events, particularly Gabby, whose biological mother Bernice returned to the village in November later that year.
In 2013, Laurel and Marlon became engaged, but their happiness was marred when Laurel was carjacked by Ross Barton. Traumatized by the incident, she eventually tracked him down and stabbed him in the shoulder with a pair of scissors; he had her brought up on charges. He would remain a part of her life for some time due to the return of Marlon's ex-wife Donna Windsor, who came back to let him get to know April, the daughter he'd never known about. Donna tried to hide the fact that she was dying, but eventually, Marlon learned the truth. His old feelings for Donna resurfaced, making Laurel insecure about their relationship. In attempts to have money for April's future, Donna became involved in criminal activities, with Ross soon joining her as well as becoming her lover. Donna killed herself and Gary North, a crime boss she had run afoul of, leaving Laurel to cope with a devastated Marlon and April. April's only comfort was Ross, meaning Laurel had to put aside their past animosity to try to help April cope. Laurel kissed Ashley and learned that Marlon had kissed Donna, making her unsure she even wanted to marry him, but they went ahead.
The stress took a toll on Laurel, and she steadily succumbed to alcoholism. By the beginning of 2015 she had lost her job at the factory and was hiding her drinking from Marlon as well as Doug, who'd returned to the village after a breakup with Hilary. When April drank from her glass and became sick, Laurel rushed her to hospital, swearing her to secrecy. When Marlon began to find out about her drinking, she tried to blame the stress on Daniel's death, among other problems. The problem rapidly sped up when April and Arthur found her drunk and passed out on the sofa, choking on her own vomit. She refused to get help, punching Marlon and severely damaging one of his corneas when he tried to get through to her. Cain Dingle gave her money to leave the village, but in her drunken state and rush to flee, she ran over Marlon's beloved dog, Daisy. He found her hiding the corpse amongst a pile of leaves, begging him not to look. She then went to a bar in town, letting a man take her home in exchange for booze, and stealing his money the morning after. He tracked her down at home and when Marlon learned what she'd done, it was the last straw. Several weeks later she learned he'd given her an STI. She tried to pretend everything was fine, and keep the children with her, but she showed up drunk at school and began calling Gabby names. At an all-time low, Laurel began leaning on Ashley, again falling off the wagon due to a conflict with him. He was run over by Victoria Sugden soon after, and a delirious Laurel fought with his girlfriend Harriet Finch at hospital, getting a slap in the process. Back in the village, she saw Sandy weeping, and assumed the worst, accidentally telling Bernice and Gabby that Ashley was dead. When Laurel learned the truth, she finally went on the wagon.
Marlon and Laurel tried again, and when they learned of Hilary's death, even went to her funeral as a couple, but they realised the marriage was best left behind. Laurel received no inheritance beyond trinkets, so reluctantly stayed with Marlon and April as she started her life over, working as a waitress at the cafe. After she helps Belle Dingle and Kirin Kotecha with their new cordial, an impressed Rishi offers her her job back at the factory. She agrees and makes plans to move into a place of her own.
