Im causing him to have anger issues?

My husband is 30, and i can see that his anger issue is getting worst than before. Hes had anger issues in the past, but he was able to be calm quickly. This time, he gets angry all the time, even on little things that shouldnt be angry on. He gets road rage all the time now, when in the past he never does. Anyways, hes blaming it on me, that im the one making him angry all the time. He said i make him more angrier than before. Idk how im the one making him more angry than how he was before?
