Really? You think someone threatening to call the police and say you were being difficult is a good person to carry on a relationship with?
Sorry, but you need to boot her arse out the door or get yourself out….no partner worth staying with should use such threats
This ^^^^^^^^^^^^^^
Get rid of her , that's some vindictive / nasty behaviour off a so called partner ,
She is a nasty peice of work mate , no trusting her after snide comments like that , the premeditated nasty thought/ threat has been well thought about off her
