Alyssa,
If your instinct is telling you to ignore the message then I think you should follow your instinct. I don't know how to erase the message without listening to it, but maybe husband can do that for you with you out of the vicinity?
I just took a call from my Mom and I'm still seething. It amazes me that she would still be interested in lashing out at me when I'm in my fifties and she's in her eighties. Sigh, some things never change - and I keep reminding myself that I shouldn't expect them to change. However, no matter how much I play "the good daughter role" , bend over backwards, and refuse her to take her baiting - she just escalates her campaign to get a rise out of me. Believe me, if someone here hadn't picked up the phone - that message would have gotten lost today.
I think that you should do what you need to do to take care of yourself. Take care.
