I guess I'm just in a phase where I wish I knew what was working and what wasn't. 97% of my DBing has really been about myself. With the little contact I have, that's been my only option. I know MDW talks about things taking longer when there is no contact.. but i don't think she meant 7 months longer.
I don't recall MWD ever giving an exact timeline of when to expect change -- she just said "could take weeks, maybe even months," which could mean any number of months. Remember, each sitch is different and may last differently according to an infinite number of variables. Some only take a few months. Or, as In_Shock mentioned with 25's sitch, could take up to two years or maybe more! It all depends on how long you're willing to fight.
Also, even if you're DB-ing like a pro, you might still also be hampered by the fact that you're on your W's time-table, not yours. Her choices are her own to make when she's ready to make them.
