Boyfriend and heterosexual friend went out for a few days, and now they want to go out for dinner with boyfriends and girlfriends. He said I would break up when I went.

If your boyfriend travels alone with a friend of the opposite sex, it means there is something wrong with him. You should take precautions, because in this case, your girlfriend will be jealous and your boyfriend will not do it if he has brains. If you go out to dinner with your boyfriend, he is not allowed to say that you are breaking up. This kind of boyfriend is not worth saving, so you'd better go, because this kind of boyfriend usually doesn't consider your feelings but only his own. I think such people are irresponsible and can't put themselves in others' shoes, which may make you feel sad or uncomfortable in your later life, because they will always only think of themselves and never compare their hearts from each other's point of view.
