There are also moments like Obi-Wan being distraught at Qui-Gon’s death and the way Obi-Wan asking after Anakin about how he’s sleeping, those aren’t the actions of just coworkers.
George Lucas even says that he put the elevator scene in at the beginning of Attack of the Clones specifically to show that Obi-Wan and Anakin love each other.
But also I think this begs the question: What is “acting like a family”? Do families have just one dynamic? Or are we basing this on the idea of a traditional nuclear family and anything that doesn’t fall into a traditional mold therefore doesn’t count? Rhetorical questions, but I think that’s one of the things I’ve been rolling my way towards lately, that the Jedi don’t fit traditional nuclear family dynamics and that it doesn’t make others obligated to suddenly like them or agree with my interpretations, but I’m not coming out of nowhere with this, either.
We see very little of Jedi worldbuilding in the movies, so picking up on things like Obi-Wan’s way of caring for others are our biggest clues–and I’ll die on the hill that Obi-Wan loved people and expressed that love just fine, that as a reserved person IRL myself, I can see some of myself there. And maybe you don’t feel that they were family to each other there, that’s fine!
But I definitely see it in the way Obi-Wan and Anakin treated each other and loved each other like family, however that family dynamic plays out, because “family” can encompass so much.
