As for my intentions with this chick.. I don't automatically move lays into the booty call department. Most of my consistent plates are qualifying for LTR. At this point I was 80-85% sold on her has a girlfriend. She showed (past tense!) consistent behavior, was flexible, giving, fun, etc. The yellow flag was her inconsistent commitment to healthy lifestyle. A long term woman is someone I intend on gaming successfully leading to marriage. I was monitoring that through the entire courtship.
So, to answer a few questions, I hadn't put her into the booty call only category at that phase in time. If she comes back sniffing around, that's where she'll be. She's out.
Prior to the last interaction, you treated her like a plate, but the last interaction (essentially insinuating you don't want to hang out if sex isn't involved) is booty call status.
She wasn't asking for exclusivity, she was asking for more attention. That is when it becomes your responsibility to have a conversation that says why you can or can't do that.
Additionally, the girl is calling and texting you incessantly so obviously she is interested. Clearly you are interested in her to some degree as well or else you would not have written this post. I guess why are you more willing to spend time checking and responding to this thread instead of one text to the girl prior to her flaking? Is it fear of rejection? Is it hoping to come across as indifferent/aloof? Is it something I am overlooking?
How many hot millennial women have you dated? P.s. it's a million times easier on the ego to think she left because you didn't want her, shows how little you understand the male.ego(understandably).
TBH sazc has the most sound advice in the thread based on my personal experience. You can't expect a woman with a decent amount of self-esteem to just be strung along indefinitely. Also, given the current dating climate, she has probably already experienced the situation previously and knows to cut ties early on now. I am not insinuating that OP should get into a relationship if he doesn't want one, I am saying that he needs to better communicate his interest/intentions with his plates if he wants to keep them in his life.
