it means she's playing you, it means she's deciding that the relationship will be run by her & her rules, you wrote it out yourself, you don't do this, you don't call me that.
It means she's in control and she can't respect you if she's going to run the show and you in the process.
Why are you pursuing relationship talk with her?
She's going to waffle back & forth, I can guarantee it from her childish, bratty behavior.
You have to stand up to her, you have to tell her that you've had it with that crap, if she wants a relationship with you, she can let you know but you aren't going to tolerate her disrespectful ways and you aren't going to waste your time, energy or love on someone who isn't worth it.
Say all of this.
She will get mad, count on it.
She may even swear at you and walk away but she will know who she is dealing with and she will respect you more because of it.
If you play into her hands, expect to be played.
What was working for you?
Think about it.
You stopped pursuing her, stopped replying to her, kept your responses bried, she had to pursue you for info, you became mysterious, you started going out again, meeting other women, yoiu became more confident, you were in control of yourself again, she did the pursuing.
If you turn around and stop all of this and act like a love sick puppy who misses his wife so much that he'll do anything to get her back, she'll read all of this and she'll know it and how long do you think she'll stick around?
Don't be that guy, she can't respect that guy and you can't respect yourself either for being a wuss.
When she comes to the office to "talk", tell her that you have some rules of your own after hearing her rules about you not calling her special pet names.
You tell her this, "I have some rules too, no more swearing, no more name calling, no more crap bratty behavior. Otherwise, I'm just going to leave, I know what I'm worth and I know I can get just as good or better. This isn't a threat, I just know myself better now and I'm not wasting my time anymore."
Let her squirm with that.
If she starts acting bitchy again, tell her you're busy and that you have to get back to work or that you have to go somewhere and if she wants to talk to you some more, she can call you later and she can tell you what she wants to talk about."
Let her work a bit for it, see if she's going to put effort into you or see if she's playing games: you know better now and you don't have to play games unless YOU want to.
