My boyfriend is often angry at my words.

His mind is really not big enough. On the one hand, he is not confident enough. Maybe he was unhappy recently and took it out on you. ) Now he may feel that he can't give you anything, so his mood is very depraved and a little self-destructive. In fact, he should want to give you a good life, maybe he thinks he can't do it. At the same time, you said that although he is good to him, it should be impossible for him at present. I don't think you can do it. Calm his mood, try not to stimulate him during this time, and pick his bad ones. Give him more encouragement, and he will be braver and feel your support.
