My boyfriend and I are young, and both very stressed with exams. No matter what we always end up in an argument at the moment, where I end up upset and he says something like "I'm sorry you feel that way", which makes me feel worse. It's as if he doesn't care I'm upset, and I have asked him to reassure me in these times, but he just claims I don't trust that he cares. He seems to be too angry with me by this point. How can I deal with this without leading to a breakup?
