"Well, I dont want her to switch things around later saying I gave up, I wanted the D, etc. "
your rush? You're only a few months into this, aren't you? The first time my WAW left, it was over 2 years from the day of the bomb drop until she moved back in. I didn't give up on her until over 1-1/2 years after the bomb drop, when she finally admitted to me that she was with someone else.
If you want her back, don't file. Just wait and work on you, and see what transpires. She might very well file on her own at some point. Then again, she might be like my wife, and never file, in which case, only YOU can decide what's best for YOU.
You should sit down with an attorney to discuss the details about divorce in your state and your situation. There are plenty of lawyers who'll do free consultations.
