Desperate need of advice

So right now I am currently going through a divorce. nothing crazy going on we just didn't work out anyways. Upon checking the case online, for a court date or zoom chat, I had decided to check my parents divorce and see how many times they had filed. In my mind growing up my dad filed maybe 4 times I don't remember but I checked and low and behold I found out they had been divorced before this last time. I didn't know I would see that. Like I feel lied to and kind of like I was living a lie like idk how to feel. I'm sure some wouldn't care but like I feel victimized. And her husband adopted me which is my dad but my mind is blown by this and my first reaction was anger. That's how I felt. Growing up for me idk if I put myself there but I was always involved and supposed to stick up for my mom and what have you. Like he had a pre nup the first time and obviously when they got remarried didn't have it that's how she got half his stuff and he made me feel bad. This was in 2017 like idk are they divorced or married right now. Like would you care if you found that out? How might you feel? I just need some insight
