My parents announced they were getting divorced January of last year. Since then it's been extremely frustrating dealing with my mother. She and I have never had a great relationship, but after the news broke I became her verbal punching bag, she picked fights with me, would call me just to say awful things about my dad, and tried to push my brother and I to pick "her side". I understand she's upset, but she refused to see a counselor and she had been really unfair to my brother and I. Shortly after I came home for the summer from college I was forced to move in with my dad because thugs got really bad between her and I. To her, that was me picking "his side". I told her that no hard feelings, but I had to move out to keep my sanity and be happy. Her and I just don't mesh well together and we do better if we're only together for a brief amount of time. Ever since then she's been distant and has showered my brother with gifts, attention, and love. I.e she gushes about him on Instagram (he asked her to post about other important things and in response she said "there's nothing else important to me"). I.e she found out my dad was taking me on a trip to make up for the fact they're letting my brother travel abroad but never let me, so she spent a lavish amount of money to take him on a snowboarding trip at a ski lodge (something I've been asking her to do with me for a year now) and they left the day after I got back. I had no idea, and called her today to ask if she wanted me to come over to celebrate a late Christmas and instead she got an attitude with me and yelled at me for not texting her "merry Christmas". I pointed out she could have texted me to (she didn't text me at all, but my brother did. I just genuinely forgot to text anyone about Christmas because I was busy. This was obviously on her mind but chose not to). There are so many more examples of her doing the little things to cater to my brother and not me.

Has anyone else ever dealt with an immature/petty/toxic(?) parent choosing a favorite sibling? I'm not saying I want to be my mother's best friend, but it was nice being on "good terms" with her and being civil. It hurts that she is so blatantly showing her favoritism.
