May Allah reward you for helping her drop that aspect of her old lifestyle. Unfortunately, women don’t emotionally mature as quickly as men do, so getting her out of that mental state of just wanting to party and have fun while being young isn’t going to be easy. It’s pretty much the reason why the Muslim ummah is going through a marriage crisis atm, the sisters would rather avoid responsibility as they follow the mindset of “girls just wanna have fun”, and they know if they get married, they are going to have to drop a lot of these “fun” aspects from their lives, kind of like in your situation.

With that being said, I’m confident that you’ll be able to make it work as it sounds like you’ve helped her mature in the past, just keep making dua to Allah and just keep letting her know how important following Islamic principles is to you. May Allah make it easy for your family, Ameen.
