Will it escalate further?

My husband has a tendency to get mad… like irate about anything really. In a span of 4 years, he’s went from being able to talk things out to throwing items around me, having road rage of speeding & driving crazy with me in the vehicle to following people who pissed him off while driving, throwing his wedding ring at me driving off to the latest of punching our closet door. Luckily it didn’t leave a hole or anything. I just don’t know if I’m provoking him to be so mad or help him not be like this.. I’m pregnant with our second baby and I don’t know if I’m overreacting or what to do. It’s just scaring me.
