The chat of anger reminds of a conversation I had with a DB coach a while back...
If you're in a place of anger and resentment, it will come across in every communication you have with your spouse. While you may think you're acting happy or "as-if" it is still there. It may be shown in your body language, an eye-roll, or unintentional tone of voice. You have to let go over the anger and resentment.
