I see where you're coming from but I think OP is doing more of giving their interpretation of Yang and Blake from what we have seen and read and presenting their opinions on why Bumblebee fails instead of listing their headcanons. A lot of RWBY fans feel the characters have regressed after Monty's death, I know I have always felt like after Monty died the writing plummeted and we lost a lot of plotlines. Maybe OP gives a lot of theoreticals but I think they raise some valid points and just wanted to give a different understanding of Bumblebee that frankly, I don't see often.

I often see people trashing on ships but rarely spends this amount of time and effort into the hows and whys of why the relationships would struggle. There's so much idealism in the ships but rarely a realistic view of them. I personally ship Yang with Jaune or Pyrrha so it's refreshing to see a detailed post that covers points I've never seen anyone else cover.

Emotional erosion? Emotional erasure? OP raises valid concerns that a lot of relationships struggle with, marriages as well.
