Shanna Moakler is sticking by her ex-husband, Travis Barker, as he heads back to Los Angeles after being badly burned in a plane crash just over a week ago.

“She is so devoted to him [and] he appreciates it so much,” a source close to the couple tells PEOPLE. “She’s sticking by him. She is with him. Despite everything that’s happened to them, they love each other.”

Barker, 32, was released from the Joseph M. Still Burn Center at Doctors Hospital in Augusta, Ga., on Monday and is headed back to Los Angels on a bus. He is “going to another hospital in L.A,” says the source. “He wants to be home.”

Another source tells PEOPLE: “Trust me, [Travis] will never fly again – ever.”

As for the state of the musician’s health, “he’s not in good shape,” says the source. “It’s still serious. It’s very serious.”

Still, one thing seems certain: For the time being, Moakler will be there to support her ex. “She’s concerned about him and hopes he’s okay,” says the source. “They’ve come to terms with what’s going on and are dealing with it.”
