Am I in the wrong?

Hey guys I just need some outside perspective on this situation in my life. My dad had a heart attack and a triple bypass in October 2019. After his surgery he asked my fiance and I to help him out around the house and with his business. We dropped our careers in Colorado and moved in next door to my dad the day after he got out of the hospital. We had been there for roughly 5 months doing everything we could to help him out and make sure he was well taken care of even though he has a girlfriend living with him caring for him as well.

My fiance and I have been together since November 2016 and we have been TTC since June 2019. I am 23 and my fiance is 32. We found out we have been blessed with a little nugget on March 30th and I didn't want to tell my dad right away because I feared his reaction as he has always been opinionated, rough with his words, and always disapproved of my decisions if they didn't go along with what he thought I should be doing. Throughout that week my dad kept pushing asking why I was nauseous and tired and I tried to brush it off before he came to the conclusion that I was pregnant. I told him I was trying to wait to tell him until a little later in the pregnancy because there is still a lot that can go wrong. His response was "well you shouldn't have gotten pregnant." I responded with "don't tell me I shouldn't have gotten pregnant"

He said" I already did and I don't see whats wrong with it" and when I asked what was so wrong about it he said" you aren't married, and we have problems." My fiance and I had 7-11-20 as our wedding date, obviously that won't happen because of the coronavirus but we have been together for 3 1/2 years and have both wanted a baby for a while. Once my fiance heard how my dad reacted, we went over and told my dad he had no business trying to control my life still. We brought up the fact that my fiance left a good job in HVAC where he had worked his way up and i left my job selling cars to come help him... all my dad had to say was "i didn't twist your arms to come out here and where would your careers be now with the virus?" So we packed up our stuff the next day and moved out of state. My dad hasn't tried to contact me to talk things out or to try and move past this and I still somehow feel guilty for leaving even though we were unappreciated and my dad acted like we owed him somehow. He would talk crap about my fiance and I behind our backs even though we were the only ones out of his three daughters and sons-in-law to come help him while he was healing. I am his youngest daughter, the only one he actually raised from birth and everything that makes me happy is wrong to him. How do I not care so much about my dads opinion and focus on my fiance and our baby and making our life better and more positive... any body else going through something similar? Please tell me I'm not crazy😭
