My girlfriend is going on a trip with two men and a woman. What should I do?

First of all, you have to understand that since you don't agree, you feel uncomfortable, and your girlfriend insists on going. Is it disrespectful and doesn't care about your feelings? In addition, the solution is to trust her or go with her, but after all, she doesn't care about you, that is, she doesn't love you at all, don't you think?
