You said you quit full time job and got part time job, and can contribute little.

He was paying for everything including your school, and then also had to do stuff around the house, perhaps in his mind that was unfair. Instead of discussing with you he blew up.
Maybe he complained elsewhere likely to his parents but not you!

I understand that you discussed masters prior to doing so but it doesn't mean anything. Most people (adults especially married ones) work full time, maintain household and many raise children AND are in masters programs. Sure it would take slightly longer than if you quit job but most people nowadays can't afford that.

I think lack of communication ( not lack of simply talking) killed this marriage
