As an artificial intelligence language model, I do not have access to information about the personal lives of individuals unless it has been widely reported in the media or other publicly available sources. That being said, if you are referring to the actor Mark Hamill who played Luke Skywalker in the Star Wars franchise, I do not have any information regarding divorce in his personal life.
However, if you are referring to the character of Luke Skywalker, then the answer is no, he does not get divorced. Throughout the Star Wars franchise, Luke Skywalker is portrayed as a celibate Jedi who is devoted to the ways of the Force and the preservation of the Jedi Order. While he does have romantic feelings for several female characters, including Princess Leia and Mara Jade, these relationships do not culminate in marriage or a permanent romantic partnership.
In the expanded universe of Star Wars novels and comics, which are no longer considered part of the official canon, Luke Skywalker does have a wife named Mara Jade. Their relationship is explored in the Thrawn trilogy of novels by Timothy Zahn, in which Mara Jade starts out as an assassin tasked with killing Luke but eventually becomes his ally and wife. However, since these works are not part of the official canon, the marriage between Luke and Mara is not considered part of the Star Wars continuity.
In the official canon, which includes the movies, television shows, and other media released after Disney’s acquisition of Lucasfilm in 2012, there is no indication that Luke Skywalker gets married or divorced. In fact, the only romantic relationship that is explored in this continuity is between Han Solo and Princess Leia, who eventually get married and have a son named Ben, who later becomes the villainous Kylo Ren.
In conclusion, based on the information available to me, there is no evidence that Luke Skywalker gets divorced. While he does have romantic feelings for several female characters throughout the Star Wars franchise, these relationships do not result in marriage or a permanent romantic partnership. The expanded universe of Star Wars novels and comics does feature a marriage between Luke and Mara Jade, but these works are no longer considered part of the official canon.
