I disagree a bit. I trained my parents early to expect a cut, and at 19 I moved with a girlfriend and never looked back.
We have a good relationship and they re good parents but I cut all attempts at having them take more space in my life than the minimum. It's so common in France we call that killing your dad (I googled and it seems to be a Freudian expression we started using to say growing up) and is part of growing up.
I have a kid now, and I want her to get the fuck out at 19, and start a life of her own with as little need for my involvment.
The funny thing is I moved to Hong Kong eventually and couldnt convince my french gf of 7 years to follow me because she couldnt tolerate being so far from her parents. I then met my current chinese wife, born here, who is in a very fusional relationship with her mom, who talks to her for hours everyday, so much she needs to kill her phone at night to stop it. And they live an hour apart...
It s clear to me there's something in Asia that's different because they all seem just as fusional (I find it unhealthy), but it may be also a girl thing more generally ? I have a sample of 2 so it's hard to know.
In any case, my daughter will be encouraged to "kill her dad" and be on her own. Even if her mom might disagree :D
