From what I know MLCs can last for years until the man/woman figures out things for themselves. There are some informal timelines on the midlifeforum website (3-5 years). O'Connor writes very well and from a psychological perspective and really explains why men have MLCs. I think Conway has a less cerebral take on it but his book was helpful as well.
It is a tough road to be on. I wish you well today.

The 3 laws of DBing:
1. PMA is critical to DBing.
2. Since drop in WAW's PMA leads to drop in LBS's PMA and vice-versa detachment is critical.
3. Validate to raise WAW's PMA and GAL to raise LBS's.
