Can I travel alone with my colleagues?

He has a family. It is immoral for you to keep a certain distance from him and destroy other people's families. Besides, it's not a pleasant thing for you to get into emotional entanglements. Even if you are self-respecting, if you travel with them, others will gossip when they know. Besides, you don't know him very well. You don't want to go unless he doesn't get married. What does it mean to get along well? Maybe your attitude towards him is so ambiguous that he mistakenly thinks you are interested in him. Pay attention to getting along with colleagues and distance in the future.
