AITA for resenting my father in a way? + i need advice on how to actually go forward with this lol

hi, i’m 15f (yes, i know im young but im honestly just asking everywhere because i have no idea what to do + using a throwaway just in case my dad is on here because you never know🤷‍♀️) , and i need help with this problem. my dad 53, is a narcissist, sociopathic man who ruined my family with my mom 53. they had been together for 20 years, divorcing in 2015 and tried to have an on and off relationship before in 2021 we found out he was having an affair with a woman in Vietnam with 3 kids, giving said kids so many gifts while i got literally a $100 on a good day. now fast forward to 2024, i had moved to Australia for a year or two because my moms mom had Alzheimers, and we moved there to help my grandmother and sell the house there before moving back here with my grandmother who unfortunately died, but that’s not necessarily the point. the point being, when we moved back I found out that he brought over that woman and her kids towards America, married her and is doing all the things he never did with me and my mom, and all of these kids have MY things; my blankets, my childhood toys, my old clothes I couldn’t bring with me, my plush animals i had to leave behind because they wouldn’t fit into the suitcase, etc. and they recently bought a house, something my father never did until i was born, then he had the audacity to actually buy a house for my mom. and he decorated said house he bought last year, something he never did with any of the places he bought/rented. and just for extra context, he had spent all of the money for the house we had on hookers in 2019, making us (me and my mom) live in a hotel for a year while he lived happily in his moms house.

recently, about a year ago me and him started to be in contact, and hes obviously been buying me stuff out of guilt. I don’t really mind, since he deserves for me to waste his money on things i dont need, and just want since hes somehow loaded with money. but its the fact he doesn’t really do anything with me? we just go out to eat, he buys me something at a store and takes me back home, which i find really boring but he refuses to drive out of my city to another one (aka a city with more stuff thats 20-30 mins away depending on traffic AND HE LIVES THERE) . i guess im just upset at the fact he feels lazy to go as far as to not take me to there, doing more fun things while we do the same thing everytime here . i want him to put in more effort with me, but im unfortunately really scared to ask since i am terrified of being yelled at by him, something he always used to do with me when i was younger. i know he probably wont yell at me, but its the fact he purposefully yelled at me at times when i was younger, making him seem mean that i don’t really like to talk to him about certain things.

anyways, i guess im just asking on how to move forward with this. my mom tells me i should use him for all the money he has since hes also done horrible things to her, which i also hate him for in a way. but i want a relationship with him, like an actual relationship where he puts effort into spending time with me and not this one hour a week to just let me eat some lunch, shop for something i want and then drop me off. i don’t know how to talk to him about this since he doesn’t really know how to talk with me, and hes a pathological liar which makes it harder for me to communicate because i cant tell if hes lying or not. Hes a very hard person to read, while he is nice to be around when hes in a good mood, its also impossible to talk him about things because it seems he doesnt want to put effort in being with me and doing fun stuff, like the most fun thing we did was go to a waterpark but he barely did anything; only riding a few slides and i only was at the wave pool the rest of the time because he was busy vaping, on his phone or napping.

i appreciate any advice given to me since i find difficulty just communicating with him and expressing stuff to him . it would actually be more helpful if i had advice from ones who dealt with narcissistic people / pathological liars before because he shows visible signs of those two behaviors and im also not sure how to navigate those . also ignore the grammar and such, im just very upset and confused on how to deal with this, i truly want to heal over the things hes done and try to have a relationship but its very hard considering at the age of 9, he made me live in a hotel with two dogs and my mom. and hes doing things he never did with me with those kids, and i guess im envious and wondering how to express to him that i want to do fun stuff with him.
