Many people who arrive at this site do so in a deep state of trauma. They don't have the perspective many people commenting here have.
Paving the way means to create circumstances that make an outcome more likely.
I think if the odds are low and the person reading this phrase is traumatized and more likely to be engaging in magical thinking (which is not meant to suggest they are naive, just that magical thinking can be a typical reaction to severe trauma) — "pave the way" can easily be misconstrued, because it literally means something that many people posting here are suggesting can be interpreted in all variety of ways.
In addition to this, many MLCers are blaming their LBS spouse for their horrible behavior. I do not think this site does enough to draw the line to say that this is not the LBS's fault. Many LBS are being severely and repeatedly emotionally abused by someone who is threatening to take their home, children, and pets from them, not to mention finances and social support (through smear campaigns). Sometimes a disordered other woman is also participating, meaning the LBS is being ganged up on by two malicious and unwell people.
In this (all too common) circumstance, "pave the way" is inappropriate, no matter how well intentioned or nuanced it is intended to be. It is not the fault of a deeply traumatized person if they "misinterpret" it, especially when this site is peppered with stages, trajectories, and other assertions (often by frequent posters that a newcomer may mistake as a moderator or true expert) that many MLCers recover.
Mental illness is so, so taboo that it is considered more serious to allege it (or brain damage) than it is to have it. A person who has a coronary event may have lingering heart damage; a person who suffers from a knee injury may have permanent ligament damage, and yes a person who suffers an extreme neurological event (whatever the cause) may have lingering brain damage. This is couched in euphemisms like "fog," but this is really what many of us are talking about.
If you read about the brain, it is very easy to see that a MLCer's behavior correlates very clearly to frontotemporal lobe impairment. This does not mean every MLCer has the same thing, or a progressive illness, but I do think this is a unifying factor of many, many of these cases.
In my opinion, treating MLCers as if they are simply jerks or awful — without acknowledging cognitive impairment — keeps many LBS stuck and not taking the correct emotional and practical actions. Much of MLCer's behavior follows very, very specific patterns. Knowing these patterns can help an LBS respond to minimize damage to herself and the people and things she wants to protect, either by emphasizing that a MLCer's disordered behavior is not her fault, or by showing her that there are some formulaic ways to respond. I feel it also helps to raise awareness too, with the hope that this will eventually help to protect men and women like us.
I think Out of the Fog is a valuable resource to this end because it presents this in a neutral way. It helps someone organize their thinking around disordered behavior without suggesting that somehow doing so will change the behavior. The descriptions are balanced and do not over promise.
HS is an amazing resource and I appreciate these discussions and the self insights because like many fellow posters I can look back and see how my ideas evolved, and what I learned along the way. I think however that it really is important to use language that takes into account very vulnerable and newly traumatized LBS.
