1: Did i get her upset by being devoid of emotion (She was the one crying and i did not)
No, this is good. You need to show her you are strong. She can cry, you dont control that, only yourself (see my sig).
As for the rest you shouldnt be having arguments, you should be validating them away, and not participating in conflict when she initiates it. Do whatever you need to do financially, do not justify it to her, do not apologize, or feel bad about it.
