Should I file first?

So a little backstory so about 2 years ago my spouse F30 asked me M33 for a separation. We separated for about 2 months and ended up back together and we were happier than ever I thought. Fast forward to 3 weeks ago she dropped the bomb on me that she wanted a divorce. After talking it over that night I agreed with her that we weren’t in a great place and it would be for the best. Now she seems to be regretting her decision and is talking about not filing for at least another 6 months. I am ready to move on and begin healing and do not want to reconcile but stay on good terms because we are not financially ready for us completely separate just yet. Should I go ahead and file now while we are still living together or should I wait until she moves out?
