Hey guys need some pointers. I'm going out with a friend of mine (HB9) who flirts with both me and my SO (is Significant Other a common term here?) frequently. IOIs all over the place. She claims she's not interested in me (or us) in that way and is currently pining for her, now former, boyfriend. (It's been a while and she didn't date him for long, he was a rebound)

Did I mention she can be impulsive? What kinds of kino/conversation would be appropriate for this situation? I'd like to get two things out of this; her to stop thinking of the lame-ass boyfriend (probably a sociopath, maybe) and potentially a regular FB for me and my SO. She's a sweet girl that just doesn't know what's good for her. ha!

I'm not interested in an stable, long-term relationship. Just an FB. She'll no doubt have BFs in the future but I wanna get our feet in the door so to speak.

Thanks sreddit!
