I do not see keeping the road paved smooth as you do. That is making it slick. You don't want her sliding in. You want her to work. B/c truthfully, it is going to take a lot more than just ending her A. Otherwise, she will move on to OM2.
Putting up road barriers would be like getting involved with another woman, going to prison, losing your job/income, causing her a lot of problems out of revenge, punishing or shaming her, and things like that. You are not placing barriers across the road. By contrast, you are putting a neon flashing arrow above your home and having a billboard sign that says you are still available and waiting. But it doesn't make her feel drawn to what you are wanting her to do. It does not work this way, to attract a WAW in an A. However, you have been told all of that in the past.
So, I suppose you will continue doing it the way your emotions dictate, until you get enough and finally decide to do what works.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
