You two need counseling. It's entirely possible that he truly is stressed out right now about work and his parents. However, lashing out at you is entirely inappropriate. Both of you way over reacted on this one. He definitely should not have followed you around the house antagonizing you, but unless you felt physically threatened, leaving the house was not a mature way to handle the conflict. (If you did feel physically threatened, you absolutely did the right thing and that's a whole other issue.)
Counseling would help him work through his stress and develop more mature coping mechanisms. It would also help you understand better way to have your needs (sexual and otherwise) understood. It would help you both develop proper argument skills. And on the off chance that you're not being completely upfront about your role in the situation, counseling might help you realize when to put yourself second and support your partner.
