Wolverine, sorry to hear things aren't going well. Since it's been a while since you actively DB'd, please read DR and then read it again and again. Also copy/ print/ tattoo Sandi's 180 DB tips (sticky at top of forum) and LIVE them. Stop the begging/ pleading/ negotiating ASAP!!! Stop pressuring your W! Do not EVER initiate relationship talks!! If she wants to bring it up then fine, but don't bring it up yourself. Act "as if" everything is fine. Give her time and space. Do 180's on ALL your faults in the M, and do them with consistency. It's good that she's giving you 6 months, but understand that it's going to take every last bit of that 6 months for you to make a positive impression on her. She clearly does not want to be married to the current you, so you've got to remake yourself. Become more strong and independent and less needy.
Regarding the book, no, Michele even says at the beginning of DR that the WAS should NOT read the book and should not even know that you are reading it. Like these forums, the book is for you and you alone.
