It is vital and necessary that you express it, because transmitting your emotions is part of couple communication.
Determinedly and using a calm tone (you don’t have to get upset), tell him how offended you feel and make him understand that an apology could change everything.
If he does it just because he has seen you very upset, don’t rush out to reconcile. Once he apologizes, keep some distance and then propose a normal approach.
Forgiveness does not have to be a before and after, nor does it have to be magnified into a reconciliation as if the relationship had ended, no, the reality is that it should be a loving habit.
