I still think she set you up with those flowers. My dad (ENFJ) trys to run that same bull.
At first, you didn't have the time/money to give her the flower you promised her. Then she bought you flowers. She already was going to hold it over your head that you forgot her but she still remembered what you wanted. Your confused facial expression was just the window she needed to get all theatrical.
My dad loooooves guilt tactics. You have to use your intuition to crush the drama before it starts or call their hand on it.
For example, if you had come with the flower the day she bought you the Amethysts, she wouldn't have been able to do anything.
Or if you had just called her hand and said "the only reason you bought me the amethysts was to gulit trip me anyways".
I'm positive you would have seen the blankest "ohh crap he already knows what i'm up to expression on her face"
I don't know why ENFJs have a tendency to waste valueable energy on drama (but maybe its because they have so much emotional energy)? Isn't it easier just to say "the flower meant alot to me, I was a little hurt you couldn't get it sooner" ?
I can't tell how many times I've derailed my dad, or sucked the joy out a possible "drama king" episode.
They're are like emotional bombs...defusing them is a full time job.
But its draining after awhile.
ESFJs are more containable because their gulit-tripping is only for the moment.
ENFJs will predict all the way down the line exactly how they are going to manipulate a sitution/you.
