I think Yang's words about the death of Summer Rose and Ruby can be taken another way. First off, Yang only says Ruby "was too young to really get what was going on," but was still torn up by it. As someone who lost someone very close at a young age, death is not something easily embraced by children. It is very hard to explain or understand the concept of death and why this happens. Even as adults, it is hard to imagine our parents dying so for a kid to deal with it fully is impossible. Ruby was sad an angry going by Yang's words, as well as some of the lines from Red Like Roses II, so it isn't that Ruby didn't know her mother died so much as her being able to fully grasp or except her death.

I also don't think Yang was trying to separate her and Ruby because of some future problems. As the song Gold seems to suggest, Yang spent a lot of time looking after Ruby and possibly being overprotective. This could have resulted in Ruby's inability to talk with other people and made her socially awkward, something Yang started to notice as she got older. It seems much more likely that Yang is trying to get Ruby to be more social and make friends of her own instead of always relying on her. The first few episodes show pretty well how bad Ruby is at talking to people and Yang is smart enough to know Ruby will need people to help her grow up no matter how much milk she drinks.
