I'm a rookie when it's comes to TRP but I need advice on getting to the next level with one of my current plates.

I've always used Red Pill principles on her cause she has a "strong" personality, to say the least, and is used to guys orbiting left and right. We've had arguments and shit but we always end up hooking up again cause of RP. Only issue is my reputation proceeds me and she won't go further until I show I'm not in this for a one time thing. Don't exactly want to make her my gf, but would like to get a little more serious with her for consistent sex. And yes she's single, not trying to mess around in other dudes affairs.

Any advice appreciated.
