I’m of two minds with this.

One is that by going to bed angry, it is unhealthy to let your body spend that many hours in an angry state. I believe that even if you can fall asleep in such an emotional state, it can’t be good for you physically.

The other is that fighting viciously all night and potentially saying terrible things you cannot take back no matter how much you want to, is even worse.

If you can work it out fairly quickly and without irreparably hurting your spouse, then maybe you weren’t all that angry in the first place?

Then there’s that wonderful make-up sex.
