“He was worried about Ava, so he came home on Thanksgiving,” a friend of Sambora, 59, and Locklear, 57, tells PEOPLE about Sambora’s holiday with Ava, a 21-year-old college student.

“They had an amazing Thanksgiving and had a private chef there so they could be together one-on-one,” the source explains. “They had a great meal and got caught up.”

Although Sambora initially planned to be in New Jersey on Thursday, “he did not want Ava to be alone on Thanksgiving,” the friend says.

On Nov. 18, Locklear was taken to a hospital after her therapist determined that she was experiencing a mental breakdown, according toTMZ.

“Deputies responded to Ms. Locklear’s home regarding a medical call,” Sgt. Eric Buschow of Ventura County Sheriff’s Office told PEOPLE. “There was no crime.”

“I will not waver on always being there for Heather getting her the best help possible,” Samboraexclusively told PEOPLEin a statement. “I am once again very proud of my daughter for her composure and strength during this very difficult time.”
