I don't have much to add that hasn't already been said, except this:

Don't mistake your relationship being better now as a sign she is changing her mind on the separation. When my XW bombdropped me, i practiced the last resort techniques, and for about 6 weeks, aside from not having sex, our relationship was awesome. When she had the next divorce conversation, I was a bit surprised, and told her things have been good, she's been happier, etc. That's when she said something along the lines of 'yeah, i'm happy now because this weight's been lifted off my shoulders and we're finally moving towards divorce.'

As others have said, try to refrain from having sex with her.
