Hello XXXXXXXXXXX,
Thank you for asking your question on Justanswer.
This can be a sign of a mood disorder like bipolar or depression. The violence is extremely concerning though especially since it is directed towards you.
The main thing is you have to think about your safety at this point. All the studies show that the abusive part in a relationship continues and increases as the relationship continues. He needs to seek treatment, or you could be in danger.
