Sounds rather similar to my own path.
I was also ridiculously wishy-washy by the time I left home, and pretty much had to create my own self-identity at the point because I had never been allowed to have one.
Our adult kids are pretty good and well adjusted human beings, too... and unlike many who came from controlling parents who did the whole "helicopter parenting" thing, our kids willingly come home and spend the weekends regularly because they want to and like being here. And I think that says a lot about the approach of letting them largely find their own way. If there was a thing I'd perhaps change it would be that we were a little to eager to protect them from the consequences of their less fortunate choices.
