Have you ever considered that that speech she gave you wasn't her trying to creep her way back to your MR as passively and weirdly vague as possible but that she is genuinely sad about the dissolution of your MR and the family while also understanding it's legitimately not going to work? Is it possible that her consideration into slowing down the D process (which isn't something she's actually done just something she said she had give some thought to) was the best version of softening the blow she could muster? And along those lines is it possible that her stating you can never really be sure about a decision like this was literal and not some code that she wants back in?
I'm just saying it seems like she was saying some pretty clear things without it being cryptic in the least yet here we are with you trying to decode it. And even if this was some coded message and she is trying to let you know she's unsure about her decision the best response to this you could come up with was a passive aggressive swipe? I gotta agree with LH on that. Validation probably would've been the way to go here but you could see the forest through the tree. You took heartfelt honesty she was offering you about her truth as subtext personally insulting you.
Last thing, why do you want a woman to "care" for you? Why do you want to be taken care of? Are you not self sufficient enough to take care of yourself? Are you lacking self esteem so you need someone to adore you to feel complete? This is not why we look for partners. Relationships are not about what people do for us. That's transactional and that is not love. Love is about what you offer. Love is about what you can do for the other person. It is not about what you can gain. Or what they can do for you.
