Hey dude,
First, I hope you're not misjudging the LJBF interpretation of you she may have. A month is a fucking long time man haha, she may think you're gay or something
Providing she just sees you as some super slick, non player, hard to get sex beast waiting to be unleashed, there's a few things you can try.
One, the classic Mystery K Close. When you catch enough IOIs in a given situation, you feel you've built attraction, escalated kino etc etc, look her in the eye, I always use a kind of 'sexily playful' smile, and just say "Would you like to kiss me?"
Either she says - 1)Yes - Kiss her!
2)Maybe/Not Sure/Anything similar - Say 'let's see' and kiss her
3)No - Say "I never said you could, you just looked thoughtful", change subject, re-escalate kino, try again later.
That should work. Other famous k-closes are 'are you a good kisser/on a scale of one to ten how well do you kiss'...whatever she says, say 'let's see then' and lean in and kiss her. Playfully rate her lower than she said after for an easy neg hit
Other less direct k closes include 'are you impulsive' followed by 'let's see' and then kiss her.
If you have The Game, read Style's words on this subject. I think this was his first major stumbling block, and he has some wisdom on it.
Peace,
