AITA For telling friends about my dad kicking me out
For context, I (20f) was kicked out by my dad just before leaving for uni last September so his girlfriend could move in. This was a gradual process as he initially told me he was letting my little brother take my room as it is bigger, I had no problem with this as it made sense. He then said a few months later that my room would become a spare room, again I had no problem with this because I wasn't really going to be there apart from christmas, summer and the occasional week off, he made it clear at this point that I would always have a space there when I was back home. He later said that the spare room would be a home office for his girlfriend.
I had only lived with my dad full time for a year due to my mums house needing renovation, during this time my dad and I had a lot of fall outs and our relationship was very strained I often felt like he didnt want me in his life and that I was the only thing in the way of him living his ideal life with his girlfriend due to a lot of things he would do and say.
He told me that I had to pack all of my things before I went to uni so he could move it all to my mums house once it was finished, this frustrated me as I was already stressed out by preparing everything for uni and finding care for my cat because he refused to take care of her after saying he would months earlier (which is a whole other story)
As my mum and I were loading up the car for the move to uni halls my dad instantly started clearing out my room, I hadn't even left yet. He also had an arguement with my mum about his behaviour towards me a couple weeks after I moved because he was demanding that my mum take all of my belongings when she had nowhere to put them as the house was still under renovation and she insinuated that he was trying to remove any evidence of my existence. His actions have made me feel like he doesn't care for me and that he feels like I have dragged him down as he was 18 when I was born.
The whole time this was happening I was telling my best friend and her parents as well as other close friends, who all knew my dad, about the situation to vent and get advice. Word of the whole situation managed to reach a close family friend/chosen family member of mine and my dads due to connections in my best friends family and she reached out to me checking that it wasn't just gossip and I told her a shortened version of the situation she was really agnry with him and immediately offered support and I think she may have spoken to him about it because since then he has been slightly more supportive and kind towards me than usual but there is a certain tension behind it that he wont address, or that may just be how it appears to me. Now im worried that telling people in both of our lives about the situation is me being over dramatic and an asshole move since I am an adult and I should be able to deal with it. I dont know how to handle this, any advice?
There is more info but had to cut short due to limit.
