For now, it seems that, as her voice actress Lindsay has said, Ruby is "married" to her job. She's too focused on what she's doing as a Huntress to be interested in romance.

It's like how Blake is too focused on what's going on with the White Fang to be interested in romance with either Sun or Yang. Thankfully, Sun seems to realize that, and that is likely why he has backed off on the whole "Hey, I like-like you" thing and has appeared to initiate "I'm gonna be here for you so you won't be facing your problems alone, and we'll worry about me like-liking you later." I mean, even Like Morning Follows Night seems to be saying that he's just patiently waiting for her to acknowledge his feelings for her:

"Every breath, every word Every smile, every glance Could be another chance That you'll finally see The love that is me So until that time I'll follow every day Every step of the way And continue to say"

I think what caused Sun to do this was Blake snapping at him for asking her to the dance. It made him realize that dealing with the White Fang is more important to her at the moment.

So, we do know that the writers can and will go with "This character is too focused on the plot things to be interested in romance right now."
