When a couple is experiencing anger toward one another it is sometimes difficult to resolve immediately. I suggest making a couple of attempts in discussing the issue prior to going to bed so the morning can provide a clean slate anew.
Coming to a resolution or compromise before resigning for the night is a good rule to follow whenever possible.
If no resolution it compromise is possible I suggest you tell one another how you love and care about them and put the conflictual issue on hold until an agreed upon time the next day.
Things won't get blown out of proportion.
Love supersedes anger.
