Preface: not claiming to be super red pill or anything but I appreciate and find TRP knowledge to be interesting/helpful for my relationships (hence why I am here).

I have been dating/banging this chick for close to 4 months now. I initiated the courtship at first and contacted her to arrange dates - heavy petting on the 2nd date (she stopped me from escalating to sex which I played off cool) - fucked on the 3rd date (about 2 weeks time). At this point I have moved to a place of letting her do pretty much all of the reaching out. average night now: she calls and we quickly get to the point of "lets hang out" if Im not busy. We get together and usually grab a bite (she readily offers to pay for dinner/drinks 50% of the time OR makes me dinner) and then later we hook up (sex is great - she orgasms every time - often multiple times and they are the full body shake kind so they're real). Up until now there has been light alluding to relationship status (chicks and their innuendos) but no official "talk". I have not made an attempt to define it as I do not see it being MY place to want/initiate an exclusive relationship so I have been just sitting back and if she brings it up - so be it. I do believe this is an ideal situation: she has not demanded exclusivity - but here is where it gets fishy to me: she has told me that she is sexually exclusive with me (not sure exactly how it came up during vetting her but she offered up that info) and is not dating other men. I feel as though I have been doing more things right then wrong with this girl, but in the back of my mind I am wondering how she could be comfortable with not establishing relationship status after 4 months with a guy who she has a high level of interest in - yet remains exclusive to him? Mind you this is a girl who has told me when drunk that she fears that I will reject her and that she "wants things to grow" between us. I am in no rush but admittedly I do really dig this woman and don't want to play the fool to a liar. She's an attractive woman so she obviously gets attention from guys, including her male roommate which I usually laugh off when brought up (although their relationship is sketchy). I suppose I will hold frame and ultimately walk away if it turns out she's lying but I just wanted to throw this out to the community and read some feedback. Thanks.
