Batman is a complex and multi-faceted character, and different interpretations of him may vary slightly. However, in general, Batman is often depicted as feeling a sense of loneliness and isolation due to the traumatic event of witnessing his parents' murder as a child and his subsequent decision to dedicate his life to fighting crime as the Dark Knight.
His dual identity as Bruce Wayne, the billionaire playboy, and Batman, the vigilante, contributes to his sense of isolation. While Bruce Wayne maintains superficial relationships and parties with Gotham's elite, he keeps his true self hidden from most people, leading to a feeling of disconnect and aloneness.
Batman's commitment to his mission can make it difficult for him to form deep and lasting connections with others. He believes that maintaining emotional distance is necessary to protect those he cares about from his enemies, who might use them as leverage against him.
Despite the loneliness he experiences, Batman finds solace in his mission to protect Gotham City and bring justice to the innocent. He may not necessarily "like" being alone, but he sees it as a necessary sacrifice to fulfill his duty and prevent others from experiencing the same tragedy he went through.
Different writers and portrayals of Batman in various comics, movies, and TV shows may emphasize this aspect of his character to different degrees. But overall, Batman's sense of isolation is a fundamental part of his identity, shaping his motivations and interactions with the world around him.
