Lost gave you a lot of great advice. And I also agree that i see a lot of 'hope' in your situation. Just keep DBing and stop pressuring her to change her mind. Listen to her and validate her feelings. You need to stop focusing on what YOU want for M right now and understand where she is at in her heart and mind. This doesn't mean that you lose hope that her position will change. She was once in love with you, she has changed her mind. The negative to this doesn't need to be stated. The positive though does... it means that she is CAPABLE OF CHANGING HER MIND AGAIN!
Also, as hard as this may be, don't focus too much on the D. I read somewhere that there are 2 types of divorce. 1) legal D and 2) emotional D. Legal D does not necessarily equal emotional D. The court process may decide the first... only YOU decide the second.
Lastly, don't feel badly about your emotional breakdowns. I cried every day for 5 weeks straight... literally. I've been better the past 2 or 3, but cried multiple times last week. It is a roller coaster man. Hang on!
