Women who do such things often seek answers.The moment I told her to grab her things and leave the room, she turned into a sweet, little angel telling me to "calm down, please" and started touching me all over, kissing my neck and rubbing herself against me. Why? Why these useless games? That's what I won't allow.
The way I understand this, she came by with baking treats, got on you about possibly being with another woman, did not succumb to being a booty call and questioned her role as being only worth so much to you.... then immediately folded on all of it when she realized it pissed you off.
She was feeling you out for more than just sex. She was looking for an answer but got one she wasn’t expecting so strongly. She folded because she didn’t want to lose what she already has with you.
So far she is complying, and will likely fall back into routine.
That said, this sounds like a kind of girl that will pretend to be ok with being a FWB, but will not really be ok with it. She is likely to raise this issue again in the future, making a bigger deal of it.
This is one reason why I often try to make my intentions clear on what type of relationship I am really pursuing with a woman: to avoid these repeat occurrences from women who do not want to openly admit what they are feeling/thinking. If I see a woman as not being long term, commitment material, I will tell them that while open to such possibilities, I am not looking for that at this time. In essence, it is basically no different then telling them to grab their sh*t and go if they don’t want to deal with that....only difference being, you should only have to do this once.
Any woman who does it again will clearly understand she is stepping beyond the line.
