So yes, this is all normal. However, a lot of times the WAS will hide their emotions. They want the LBS to think they are sure and confident in their decision to leave. When they do show their emotions it is usually to manipulate the LBS. Likely he is trying to weasel back home. Don't fall for it.
This describes my WAW. Not to hijack, but is the only suggestion to keep DBing and let the WAS make the determination of the next steps?
How do we know what is manipulation and what is sincere?
