Eh break up with Cait...

I for some reason want to make all my characters non-dogmeat companions get ticked off at my character For fun
I've moved onto Cait who my character is in a relationship with after she beats the chems
And I've read that once shes clean killing non-hostile settlers or taking drugs in her presence are 2 things she dislikes
Yet when i kill said settlers i never get the "Cait disliked that" thing on my screen
And when i took drugs it did work but only twice, i took them a lot so how do i get my character onto Caits bad side?
