Generally speaking, you can achieve your goal by irritating your boyfriend with one sentence, saying something that is particularly sensitive to him, saying that he cares about him, or saying that it hurts his self-esteem. For example, if he cares about your feelings, you can just say, "Let's break up!" This will make him very angry and angry. However, I personally think that no matter what conflicts arise between couples, don't say so to hurt each other. If you are dissatisfied, communicate more to solve it. If it really can't be resolved, you really don't want to maintain the current relationship, and there is no need to do so. It's better for everyone to get together before leaving. It is the best way to make it clear directly and bless each other generously.
