I love her, but she's the only person that stresses me out 24/7. She tests my boundaries and gets mad when I actually snap, is overly dramatic, and thinks that she's always right, and when she's not she'll still try to prove she is days later. She irritates me so much and my patience with her is so thin.
One time we were in a car, she was driving. She kept reaching over and touching my leg. I told her to stop multiple times, and that I was serious. When she didn't stop I raised my voice at her and told her don't touch me and she got upset, and said don't speak to her like that and to just tell her I'm not in the mood.
Another time I asked if she wanted to pick my friend and I up to hang out. I clearly stated that she don't have to and that this was a last minute idea we had. She does, started scolding me for not telling her a day in advance, and takes a stop somewhere before we go to the planned area. She forgets to put her car in park and hits the gas on the way out, causing it to go over the curb and hit a gate, and started yelling at and blaming me.
And then she has a breakdown when a cage doesn't fit in the car, abandons my friend and I in a parking lot, and have to wait for her mom to get us.
Something that ticked me off internally recently was when I was sick and tried to give me 3 year expired NyQuil that had been opened. When I told her you're not supposed to take and that it's ineffective she denied it, and a few days later made a comment about how it's fine to take it.
Another thing is how she shares EVERYTHING about me. Never herself, but me. Whether it's how I got overwhelmed or sick or something that I told her not to tell anyone, she does anyway. And then she wonders why I don't tell her anything
These are a few examples out of the countless times and other occurrences
I've already tried telling her how I feel about these things but she either undermines it or just repeats it. We do have good times together, but she gets to be too much very quickly and never understands what she did.
