I kind of laughed to myself and reminded her how she was with another guy two weeks after our break-up and this current guy three weeks after our last break-up. She didn't respond back to my text. About thirty minutes later I asked her if she still wanted to have dinner, which she replied "No, I don't think that would be good right now."
...
It does make me curious as the why she changed her mind about dinner and if I am going to eventually hear from her.
because you hit her with a barb, and it struck a nerve, and it sounds like she changed her mind as a result.
So, I am assuming she is wanting me to chase her,
there is nothing that you report that would suggest this.
on the contrary, after the barb, she balked at getting back together, and you pushed, and then followed up with trying to rekindle more old memories. that is chasing her. but it chased her in the opposite direction.
if I am going to eventually hear from her.
probably not. i think the question is what you want to do here. do you want to get together for dinner? do you want to reconcile the relationship? do you want to move on?
if you want to crack the door open, it might help to apologize for the barb. if it were me, id say something like "hey, i gave it some thought, and i feel like what i said the other day was kind of a dick move. i was speaking out of hurt, and it was wrong of me. im sorry."
id probably leave it at that, and gauge her reaction. if shes responsive, i might mention "if youre interested in getting together sometime, id love to. if not, no hard feelings." she may or may not be hesitant, but if the two of you keep in touch, she may become open to it again.
