I hope Rey does away with the attachment thing and all the prequel Jedi dogma and has a family.
Following that nonsense didn’t work for Luke Skywalker in the Disney timeline. His rejection of it in Legends and starting a New Jedi Order was better.
Did he really explicitly reject it in the EU? I think Luke explicitly rejecting the anti-attachment dogma is more like a retcon, since all those stories about Mara Jade were written before the Prequels, and writers like Timothy Zahn never imagined the Jedi would forbid romantic attachments.
I think the OT pretty strongly implied the Jedi were allowed to marry and have children. I mean, clearly, Anakin had children, and nothing in the OT indicates this was somehow bad or out of the ordinary. Anakin’s fall to the dark side is never connected with romantic relationships or attachments in any way.
It’s really amazing how badly the Prequels mesh with the OT sometimes.
