I don't know. I get the desire for Rayna not to have genuine feelings for Luke because he's a useless tool, lol, but this woman has children- dragging them into a marriage plot for her career isn't HBIC, it just makes her a bitch who's a bad mother. And crushing Deacon for her career wouldn't say much about the depths of her feelings for him either. I more think Rayna has decided Luke being the "safe" choice (as much as I have zero sympathy for this logic from her given that she literally JUST divorced her previous safe choice) means hey, she does love him, even if she doesn't feel it deep down.
