Hi and welcome. What a great story! Kudos to you for getting yourself enrolled at school..
Part of me wishes I could open her eyes but on the other hand I dont know if would want to take something from her that is such a big part of her life. My sister is still there too. I feel like they are lost in a dream land some where out of touch with reality.
I can so relate to this. It is so tempting to throw some crackerjacks into their lives by giving them a picture of how thoroughly they've been manipulated and what a waste all of their efforts are. But... they're happy, at least they think they're happy. Sure, we're happy, but it took a long time to get through that ugly period of confusion and get to the happy part. They are definitely lost in a dream; a long way from reality, but I think that as long as they're where they want to be, they should be left to it.
The moment that any of them start questioning things and getting confused and I hear about it, I'll be there for them, but as their happiness is their own responsibility, I'm letting them be for as long as they think they have all of the answers.
