When she was alive she seemed more interested in Kakashi and only cared about Obito as a friend. When Obito "died" after being crushed he regretted not telling Rin how he felt about her, so we know there was nothing going on between them before then, unless it was some unspoken mutual feeling no one picked up on while reading.
When Obito is killed by Kaguya, he saves Kakashi so he can have "alone time" with Rin. When he gets there, she's excited to see him and says she's been waiting for him, and applauds him for trying so hard to save the world. So we know they're about to do some "private things" which is why Kakashi needed to stay. Then Obito is about to leave and Rin is basically like:
"But baeeeeeee you've kept me waiting so loooooonggggg ugghhhh"
And Obito is like "Gotta make sure Kakashi doesn't show up anytime soon. I'll be right back c;"
Seems to me Rin is mad horny and Obito wants Kakashi to stay alive while him and Rin get it on in the after life.
Just seems weird Rin developed sexual attraction to Obito while dead.
