Their marriage lasted a mere six months, and imploded fast and hard on the Teen Mom 2 season finale, but Corey Simms will always think fondly of Leah Messer.
"Corey still has feelings for Leah," a source close to Simms says.
"She is the only girl he ever wanted and he's ever really loved."
By late last year, Leah Messer had clearly moved on, accepting an engagement ring from Jeremy Calvert. She got pregnant by Jeremy, but later had a miscarriage.
For Simms, moving on hasn't been as easy: "Corey is trying to move forward with life, just as Leah has done," the source says. "He is trying hard to get over her."
Leah Messer, still only 19, and Corey Simms, 21, have always had a rocky relationship. The two dated for one month before they found out they were expecting.
They split after the 2009 birth of twins Aliannah and Aleeah, then reunited six months later. After moving in together, Simms proposed. They wed October 17, 2010.
Messer filed for divorce the following April.
"Corey wishes his marriage would have worked out but he knows it's over. He knows in his heart he did all he could do to make it work," the Simms source says.
"Part of him still wishes he and Leah could work things out, but for now he is staying busy working on his new house trying to get it ready for his girls."
