>Homura isn't acting on romance
Because she doesn't feel it
>Homura doesn't make sexual advances towards Madoka
Because she has no interest in having sex with her
Both things that were said by the literal writer of the show
>Homura has a tangible 2-way relationship with Madoka
But everything she does leads to that 2-way relationship coming to an end or at least becoming much more distant. Thus proving that this 2-way relationship isn't her motivation and she doesn't care about it that much. She doesn't care how Homura sees her as long as she's safe and happy.
