AITAH for blowing up at hubby's bf's wife

Hubby's friend and his wife came over for dinner. We had a taco bar. Everyone ate and I was cleaning up. Hubby and hubby's BF have disabilities so I told them (naturally) to sit and I'd get it. Hubby's bf's wife has NO issues but sat there watching something on her phone (which she'd done since she'd gotten there). She said to me "Don't wait on MY HUSBAND. THAT'S MY JOB" to which I replied "Then get off your ass and help me!" We haven't heard from them since
