Yeah, on a more practical note, the liftoff lemmy app has lemmy.world baked in (and makes it fairly easy to add other instances to) which is a fairly big instance so its all feed could be a good point to start adding stuff in a fairly straightforward way. Not saying that’s as good as adding better discovery to mainline lemmy, but maybe a somewhat low barrier option to share with people who might find it useful in the meantime
Well you could start by not calling her attempts to make advances “childish”. In those instances when she does her advances, how exactly are you communicating with her? How do you react, what do you tell her?
If she’s genuinely trying to be affectionate with you but gets shut down, it’s not hard to see why she wouldn’t be partiularly into it. So it definitely would be a good idea to find out how she feels about your reactions to her advances.
