Is AUTHOR wrong in the post ? POST : Just by the title alone I can imagine most people would say that I'm the asshole, but you have not smelled his farts. They are Chernobyl-levels of toxic clouds that no one should have to simmer in. 

So last night it was one fart after another and I was trying to sleep. Just when I felt myself drifting off, another wave of miasma would hit me and I would have to turn over and filter the air through my pillow until it was safe to breathe normally again.

At one point I said "I'm about to go sleep on the couch" because I would never suggest he have to leave the bed. I am more than capable of removing myself from the situation.

I think that offended him because he just said "goodnight" and got up and left.

The title says that I "suggested he sleep on the couch" because I think that's how he saw the situation when I said I was going to leave, so in his mind, I suggested he sleep on the couch rather than myself. 

Now, he's being very short with me and sort of giving me the cold shoulder. I know he's mad at me, but it was his decision to go sleep on the couch, no? No one forced him to do anything or leave the room. Should I apologize?
