"There was a lot of tension between Chris and Greg because she spent so much time traveling with him during the marriage that she was not home enough with her three teenage sons," a source close to Evert tells PEOPLE. "She regrets that and has changed her pattern. She is enjoying spending more time with her boys. She loves being a mother."
Evert, 55, spent Christmas in Florida with Alex 18, Nicky, 15, and Colton 13, then over the long New Year's weekend flew to Hawaii with Colton, a friend of his and one of her girlfriends.
"They had a blast," the source tells PEOPLE.
Evert and Norman, 54, finalized their divorce in December at the Monroe County Courthouse in Key West after several months of separation.
"It was painful for Chris to have to deal with the divorce now and the separation earlier," the source says. "She would have preferred to have it all done at one time."
Evert had no comment on the divorce. Norman's lawyer, Jeff Fisher of Palm Beach, tells PEOPLE that he too has no comment.
