Am I wrong ?

My dad has always been in and out of my life like growing up I saw him 1-2 times a year. Until now at 22 I thought that was normal I always have put him on a pedestal. Every time he’d come around he’d buy me stuff so I thought that was ok. I was taken from my mom at 8 years old and he had a chance to save me from going to foster care and he signed his rights over. After being in foster care for 8 months my family in a different state (my dads sister and mom) got me and separated me from my sister because my sister wasn’t related to them(we had different dads). So anyways fast forward 6 years I ended up being too much for my family to handle. They said I had a bad attitude. 🤷🏻‍♀️. Well they sent me off to my dad he lived in a very small town and was on worker’s compensation. He has always been on drugs really bad he was on crack and recently moved to meth but anyway we always had a place to live the 1.5 years I lived with him from 14-15. Then he decided he didn’t want to do workers comp anymore so he went on the road (he was a traveling electrician) and left me with my mom. Well my mom wasn’t exactly perfect and I loved her but she let my boyfriend move in pretty much the same week my dad left so he would pay the bills and now 7 years later I am still living with him. So anyways now I’m 22 and my life is great. I have 1 child and 1 on the way. We have a brand new car, our credit is on the rise and we have a very stable life 4 hours away from my dad. My dad has asked me to use my credit to get him surgery and I can’t do that because he doesn’t even pay his bills that I pay for him much less a whole surgery and I felt so bad for saying no. He has tried to get me to use my credit to buy him a house I don’t even have my own house yet we rent. He has wanted me to give him vehicles and I have given him 2! 1 truck he only paid what I paid (we flip vehicles) and I have him a Honda and he gave it to his girlfriend. My dad was shot 1 year ago and I dropped everything. I lived at the hospital for a month while my boyfriend and my son was in a hotel for a whole month. I had just got a settlement from my moms death (she died as a passenger in a car wreck) so anyways living their for a month in hotels and having to move my dads whole house I used pretty much the whole settlement. He was in the process of finding a new place to live when he was shot. After he woke up from the coma first thing he did was talk to his girlfriend which is the reason he was shot. She’s 26 with 4 kids. My dad is 45. 🙄 she only used him because he makes good money. He wakes up talks to her and because I expressed my concern he said some aweful things to me and he takes shit about my mother who was dead at this point so then we didn’t talk for a couple of months. But I don’t hold grudges. After a couple months his girlfriend left him again and he was ready to talk to me again so we had OUR normal relationship again. But every time he calls me it’s for a favor. My boyfriend is a very good mechanic and he can build a vehicle to make it really fast and my dad loves racing etc so anyways he only calls me because he wants my boyfriend to build him a truck or his mustang or something. Well now he has 5 vehicles all blown up and a truck that’s wreck (which he wreck on my insurance, it was his fault, he pulled in front of an 18wheeler so now Also my insurance is probably gonna sky rocket! I have never even had a traffic ticket) because he’s an ignorant driver and my boyfriend is busier then ever in life, He owns a business and I’m lucky if my son and I have sunday with him. So my dad actually expects us to drive 4 hours (mind you I’m pregnant with terrible sickness I’ve been loosing weight and can hardly eat) and he wants my boyfriend to work a whole weekend fixing everything. Like whole ass engine jobs! And he doesn’t pay us ever! I actually have a few of his bills come out my account and it’s like pulling teeth to get the money from him. So anyway I guess I have a lot of built up anger and we got in an argument and now I feel like a selfish ass person for not helping him because he is stuck at home. Then he plays guilt trips saying he grew up with no love being thrown out at 17 and was raised to be a hard person well I can only think I was thrown out my whole life from 8 years old. I have been on my own since 15 but apparently what I went through doesn’t count. And I’m just sick of it. I want to cut him out of my life! I did t mention the 1.5 years I did live with him was very abusive. I use to be scared of dieing when he would come off drugs because he would choke me. One time he went head on with an 18 wheeler playing chicken screaming at me because I missed the bus(which I actually didn’t the bus just went right past my stop). Anyways this is besides the point I guess I’m getting at am I wrong to cut him out. If he ever gets shot again or a car wreck like my mom I don’t think I could forgive myself. Idk if anyone is going to actually read this whole thing but if you do could you let me know if I’m wrong? Or maybe what to do? (Sorry if any misspelling and I tried to make it short it’s a long life haha).**theres so many things I didn’t even mention because we would be here all day so I tried cutting it, but many other things he’s asked of me and many things we have been through**
