What an opportunity, a friend going thru the same thing.

I know it suxxors, but what an outlet you can be for each other.
Get each other out of the house. Watch and listen to how he sounds, how he looks, how its affecting him. Do/are you acting similar, does it look unattractive? Help each other.

Practice listen, validate. HEAR whats being said. This gives you a chance to see what you look and talk like maybe? You can do this while helping a friend thru a tough time, but use those resources for your benefit too. You both can.

I certainly understand the "dread" interactions. We all go thru that phase. Its good that you realize it, something to work on.

If you need that break, take it, but don't do it in anger.
