My partners ex wife is a nutter-I could write a book on her tricks to try to break us up
(Think ringing us every single day to scream down the phone,has had him arrested-she punched him but rang the police to say he’d hit her,told lies,bad mouthed him to the kids,kept ringing my In laws to scream at them,she once tried to tell him that she’s banning me from walking through the doors in my own home-oh,the list goes on (but I once saw her in the street and she ran away)
Anyway after almost 7 years she calmed down a bit-it helped we’ve changed all our phone numbers and have a burner phone just for her,which we only turn on to check for messages twice a week
She still thinks nothing of texting him to whine for more money or to hint for help when she’s got herself into another problem and needs help (I’d be the first to say he should if she hadn’t caused so much shit for us) so I tend to leave him to deal with her-he will then phone her back if it’s important
I wind her up by doing things like wander into the room,and ask if he’d like a cup of tea or that I’m ready to go etc
It’s petty but it really winds her up knowing that I’m lurking in the background but she can’t do anything about it as I’ve not done anything wrong and if she starts screaming,he just puts the phone down and turns it onto silent so she can keep ringing-we don’t hear it
