I should preface this by saying I've been a lurker for a month or two, I've read SGM and MMSLP and I've been attempted to incorporate TRP into my life for the past month. I'm still a newb but I'm learning.

Sex hasn't happened for almost a month now with my current gf when it used to happen all the time. She's still fairly physical with kissing and other touches, however sex just doesn't happen for whatever reason she has that day. Very recently however she's been extremely hot and cold and the shit tests have really amped up. Small things from asking me to get up and get her drink when we're both sitting down to mentioning how horny she is on social media (it's a mostly private account that she knows I know about) but never directly telling me. The latter infuriated me and sent me on a 2 day monk mode reading the above mentioned and many many TRP posts, although I somewhat countered this by posting a new haircut on FB and getting many positive responses from some plates (at least I think so).

I've accepted that the end is now beginning, if it hasn't already happened, as she's very attractive and with many orbiters.

tl;dr - GF is pulling away from me sexually and being aggressive in some interactions with me, she seems to be getting ready to branch swing. Does anyone have any quick tips, or helpful thoughts to help flip the relationship dichotomy around and regain frame and control in small period? I know that "quick tips" aren't truly a thing in TRP, but any small bits of advice for things I can do would be very helpful.
