Angry husband

So I started on here trying to figure out what is going on in my marriage.. At first thinking my husband might be narcisistic or maybe even sociopathic (ASPD).. And then thinking he might be emotionally abusive.. leading me to believe that my overly passive, codependant nature is enabling him to be this way.. But after even more racking my brain, I am now at the point of thinking that he is not abusive, but just has unhealthy anger issues (along with other issues stemming from his messed up family /childhood trauma). Overall we have an awesome relationship. But on rare occasions, he can reach his limit and go off into an angry rage (with name-calling, belittling, door slaming, etc.). From what I know of him and the love I've seen in him, I have to believe that he is genuinely a good person who sometimes does bad things. I would love to figure what to do in those instances, and ultimately how I can approach him about this issue to help him overcome.
