I believe what you are looking at is a weak relationship style from both sides. The fact that an argument after a rough day can turn into this shows that both of you havent made the right mental arrangements that would show you are in a stable relationship with each other. It doesnt matter who said what and when and who was right. Yes, he should have helped you with dinner ...maybe in a safe relationship you would have been able to say "Oh well...dont worry then. It's not nice but we'll get over it". Likewise he could have looked over your remark that might have come across in the wrong tone and thought "Oh well, she had a real bad day but I'll try and chear her up". He certainly could have told you about leaving but also that wouldnt neccessarily be the point to break it off if you manage to resolve it afterwards. The point is with you guys one bad reaction lead to another bad reaction. Maybe you are both not ready for it....it certainly feels very complicated and there seems to be a lot vulnerability and big egos involved (he does something that hurts you and vice versa). I don't know if "standing up for yourself against him" is a great basis for a loving relationship. You shouldnt stand up against each other. well, you shouldnt have to at least. You havent done anything wrong - it might just not be the right thing for you both at the moment.
