Yes, you should accept that she wants out. She wants out. It is a fact. Why should you deny it?
Your pursuing her and chasing her is not going to change that. Leaving DR around is really not going to help, hopefully she did not thumb through it.
Rather than being in denial about what she wants, or trying to psychoanalyze her to figure out why she doesn't want what you want, or applying pressure to try to shape her wants into yours, yes, simply accept that she wants out.
It doesn't matter why. You can't fix it. Accept it.
Instead, work on yourself so that at some point she might want back in.
