My point is that there isn't a lot of "material" to dive into the question of "marriage/romance among the Jedis": Star Wars (the original trilogy) is basically a Swashbuckler in space, with all the associated trope of the hero building up its crew and his skills to fight the final boss, and the only romance that is developed isn't about the main character but his sidekicks. Maybe it was avoided for Luke specifically because of the "no-marriage" rule then ? I don't know, I'd rather say it wasn't developed because it isn't that interesting for the plot. But that's just a wild guess.
