7 months isn't that long to really know someone but the honeymoon phase is waning. If he acted like this for a couple of arguments, how do you think he will be if you spend a lifetime with that behavior? He is being emotionally abusive. One sign of it is you are blaming yourself already. No one behaves perfectly in an argument but irrational behavior is a sign of something worse on his part.
Listen to what the others are saying. This isn't about the alcohol at all. I've been in severe pain and I never treated anyone poorly.
