Child of a cheater

I'm 23(f) and just recently found out my dad had been cheating on my mom. I dont really know if this is the right subreddit for me as the daughter of a cheater but I just have a lot of feelings and dont know where to put it. I love my dad, but I just feel so gross being around him. It feels like every part of him is contaminated and hugging him or being next to him feels violating. The person he cheated on knew he was married with kids and even talked about us (his kids) with my dad. She even went as far to try and gift us things so dont give me the whole "misplaced anger" talk. They're both adults and they both suck. I have never been so sad and grossed out and I just cant fathom how someone could do this but at the same time i miss my dad so much. I wouldnt wish this pain on anyone. Once again sorry if this isnt the reddit for this feel free to delete if so!
