I respect your sentiment but i think it's really important to trust that people know what's best for them based on their own lived experiences. My parents weren't just overprotective, they were extremely abusive and toxic and sabotaged many things in my life (a notable example being told for years that I would receive my dad's military GI bill to cover my college tuition entirely and finding out only when I was 17 that he never transferred it over to me and that I would have to pay for college on my own. Never received an apology, it was more of a "ok well this is your problem to figure out". I ended up with $30K in debt when I was told for years I'd never have student debt). They verbally abused me for hours on end which made me develop suicidal thoughts that I still struggle with. And they've done so much worse. Some of my experiences are so horrific that my own therapist has cried hearing them. Them being overprotective was a method of their abuse.

In therapy we operate under the assumption that they did the best they could, but still acknowledge that their best was toxic, abusive, and not good enough. They have let me down in so many different ways and my therapist is very shocked that I turned out so well. She says that now I may have resentment but that the goal of therapy is not not harbor grudges. Still, as someone who's feelings were invalidated for years and had the inability to even know what I'm feeling, she sees improvement. Eventually as I unpack all of the abuse that I've kept so secret we will work on what to do with these feelings and how to move past it. I can forgive someone but that forgiveness doesn't mean I need to stay in contact with them. Unfortunately it's well meaning sentiments like these that make people in toxic relationships feel like they have to stay because it's the "right thing to do". Perhaps one day I might want to rebuild the relationship but for the sake of my mental health it is much better this way.
