Sorry had to rant. Sorry its long but i just needed to say it.

So im 16 and i went to my aunt's wedding with my dad. First time ever he took me somewhere. Which i found odd because he's a narcissist and believe women do not have rights and only supposed to do house work and to please a man only and break people. Plus when he's around others he's two faced. So he took me to the wedding and the only people that knew i existed was the people in my family but i only knew 5 people. I don't even recognize not even my own family but 5 people. I only seen photos of theses people. So i just sat down at the close family table. my dad grabbed my arm and pulled me out side and said that's not where you sit you good for nothing brat, you sit at the kids table so u can watch them and "we" can have fun. I just wanted to scream at him and tell him to f*** off. So i walked back in and went to the back and guess what my new uncles mom came up to me and said hey you you work here why don't you take my dress to the back and then point the guest to everything. My new uncle figured out what happened and had to tell his mom im not a worker shes my new wife's brothers daughter. I just stayed quite and just done what i was asked and had to watch the kids at the same time. Man if you wear black dress pants and a bright green blouse i guess you must be a employee. I had no fun and litterly i had to help do everything and i had to get my dad dressed because he's over 330ibs and he cant even get dressed or tie his shoes. I swear i just wanna hit him. (It was my dads responsibility to buy me a dress for the wedding but i know not to trusted my dad he totally forgot but he never bought anything for me ever and the only thing he cares about is keeping the face of the family looking good and me obeying demands and keeping the family name in the family and in all honesty i just wanna switch my name to just not be in the family anymore.) I didn't eat because i was to busy so my aunt came up to me and asked why im not eating? I just said because im never supposed to eat around people because its rude and if im needed i would of have to throw it away and im not allowed to sit at a table for family. She just looked at me shocked and just walked away. I just never cared. When wedding photos came they said i have to be in them so the family will be whole and we can keep face. I hate my family. So on the way home my dad yelled at me for being so rude and i should of said good things about him and to keep his good man look up. (Ohhhh heck no i hate him and is it bad i just wanna hit him.) He just decided to drop me off at walmart with my stuff and i went home crying with my mom and me texting my boyfriend.

Why should i ever go back to him i haven't seen him in over two months he hasn't even seen me on my brothers birthday i haven't been down there since Christmas and in all honestly i never wanna go back will this turn into a soul custody concern or can my dad fight for custody to get me back and do i even have a choice in it?
