This up coming monday is my couins birthday and I dont like her there for do not want my mom bringing her to our house on her birthday. Backstory on her, she recently moved to my town from where she was living before and has made my life hell. She is the type of person that will let you know that she is the smartest in the room (she has a PHD). She is also a Phsycologist and tries to analze you everytime you speak to her. The last issue I had with her started when my mom asked me to pick her up from the air port. And did just that. YET it became such a big issue that my mom and I got into a fight all because of her. She started saying how I disrespected her and how I was rude, then chimed in my aunt saying that I was rude to her too because when she had called me on the phone WHILE driving I was dry while speaking to her (I was driving my moms new car and was very scared). This then spiked a fight that lasted A WEEK with my mom because my cousin who is by the way 29 about to hit 30 could not speak with me who is 20. I then tried reaching out so that we could speak and even speak with a counselor to try and fix things. She left me on read. This was back in january now we are in may and since then have not sopken. Now her birthday is coming up and my mom has let me know she will be taking her out to dinner and all I asked is for her not to bring her over because I sersiouly do not want to see her and of course my mom got mad at me. Now am I the Ahole for asking that or should I learn how to suck it up?
Also just want to add: No, she was not in my life until recently and No, she did not celebrate any birthdays with us. She also claims that she moved for my mom which is a lie it was for her BF AND on top of that she hid her engagement from my mom. The only reason we found out was because her mon called my dad to tell him to block off that part of 2027 for the wedding. My mom had to text the cousin to fond out she was enganged
