While Puppy might have phrased it better, you have no idea how frustrating it is to read how you are doing all the wrong things. I'll give it plain with only a touch of a 2x4:

1. NO MORE TALKING ABOUT THE RELATIONSHIP! At all!
2. No more excuses why you have to answer the phone every time
3. Not one more word of her about, "what, you're not talking to me now?"
4. No more telling her how she said, "I love you and don't want a divorce". (Why is it that DBers are really anxious to "believe none of what they hear" when it's bad stuff, but really ready to believe all of what they hear if it's positive?)
5. No more acting like you are crushed.
6. Basically, give her space and continue to give her space. Accept some, but not all, contact and be cheery when you hear from her. Don't linger. Don't ask how she's doing. Don't remind her of anything she previously said. Don't act like your world is collapsing.

Come on buddy...start DBing
