TLDR nothing have happened, made her take responsibility, any escalation plans delayed until she initiates it back herself.

She have made another suggestive comment as I was airy in the head since I have recently woken up, "You are prolly fantasizing about something.." and I reflected it back on her "What I am fantasizing about?" no comment from her / ignores me, then I continue with "If anything you are only one fantasizing about something." she reacts with "Yeah.." and I continue with "You cannot just name it." and leave her hanging like that. After she finishes with her stuff she returns back with "I was thinking about how I need to rest and get some good sleep." No comment from me. Movie ends, she is about to leave my room and I ask for her attention "You know what..? You are the one that makes those comments yet you are unsure about it and cannot name it. I know what you are thinking about." Then it's basically a few of back and forth of me not answering her and she was like "What I am thinking about? What do you know?" she was like seemingly pissed as she was hella careless about it. After some time she returns back, asks same questions but I react to it in passive-aggressive way basically something like this:
"We have been through this already and you haven't made your mind. You are unsure what you want yourself. You are being selfish and you don't think about my own health. it's not healthy for me, when you will be sure of what you want, you will initiate it back yourself."

Feels good. I think it's way better than my previous approach I was about to do, it's not prolly the best way to the "success" yet it is one of the most healthy ways for me to proceed with this, with the most healthy one being is to stay my boundaries and tell her it's inappropriate, toxic and damaging if she will continue without clarity, I will most likely proceed with that.
