here in my location no this would not be called abuse. its not a nice thing to do I agree but its not abuse here where I am..

you see each state, city and town in the USA has their own laws and standards of what is abuse.

to find out if this is abuse in your own location you will need to contact law enforcement, a doctor, therapist or other person in authority that will know what the laws and definitions of abuse are in your own location...

that said there are things you can do in this kind of situation ...

walk away, not just to another room walk out of the home and go for a walk or to the store or other location with out this person.

go to the bathroom and lock the door, in the bathroom have a pair of headphones, music player or other device you can block out everything except your own thoughts,

take a shower. most people cant hear very good when they are under the shower faucet.

get some cleaning done by turning on the vacuum cleaner and vacuum or other noisy housework ...

my point is you cant control her and what she does but you can control you. only you can decide whether you want to listen to her attempting to keep a lovers spat \ or arguement or other actions where she feels she needs an answer right away but you are not ready to answer right away. only you know what activities and such are available to you when you need to have some alone time.
