So I know that I've been in the friend zone of this girl for a while, and about a week ago I decided to outright aggressively try to get out of it. We've been texting a lot, sadly I haven't been able to meet her much in person. Anyway, I've managed to turn nearly every conversation sexual somehow. I've made small roleplaying games where I talk about us as lovers or a married couple. To my annoyance she hasn't really picked up on the roleplaying part, which is an IoD I guess. However she hasn't at one point rejected me, she has simply sometimes changed the subject or twisted the topic a bit.
I thought things was going well, because about a week ago she started complaining about everyday annoyances. I kept changing the subject, and the past days she hasn't started that kind of conversation with me. However yesterday I got a slap in the face where she in the middle of a conversation about exercise and body, she asked me this:
"btw, what do you do when you're kinda mad at your BFF and she suddenly texts you "I miss you"..?"
I instantly replied that "I'm not your psychologist, ask one of your girlfriends

" (Note to self: the smiley was unnecessary).
She then said that "None of them are online!"
I replied "Then you have to think for yourself."
She kept going by saying "I did, and I didn't like my answer very much :/"
I broke it off by saying "Then you should have answered something else, .." directly followed up by a completely unrelated question.
Having her ask me stuff like this is a clear indicator that I'm still deep within the friend zone (I think), and my attempts at changing this through texting seems to have failed. What I plan to do is meet her in person and try to escalate some kino, but if that doesn't work I'm at a loss. I'm meeting her later today, so I'll post how it went in this thread.
Does anyone have any tips or points of evaluation? How can I make her realize that I don't want to "just be a friend"? Should I make any attempts at voicing what I feel or is this a strict no-no? Girls are confusing :/
