I miss my old flip phone - when ex started to spew at me on the phone I would slam it shut. If he called back I would say "Sorry, I must have driven through a cell phone hole." Eventually he figured out that every time he spewed I would mysteriously drive thr5ough a hole.
Eventually I trained him to communicate by email only - much less stressful for me. If he called I would let it go to voicemail and text him back. If he texted I'd say "I just sent you an email about that".
