A couple of months ago, my gf and I had a small argument over being banished to the couch. I said there's no wayI'll ever sleep on the couch just because my wife said so. She said that's just how it goes and I will. I said no. Then we went back and forth for 5 minutes.

I don't understand how adults can take this behaviour seriously.

NOTE: We've been dating for a number of years

EDIT: She wasn't actually trying to send me to the couch, we were having a philosophical/idealogical argument.
