Ditto Sassy. Deejay, you wouldn't be the first person that wants their WAS to read some literature, or leave books and articles conspicuously around the house for them to read, or email articles to them, yadda, yadda.
"A person convinced against their will
is of the same opinion still."
Besides, it's seen as you pushing your belief system unto theirs, which automatically raises their defenses, just as proselytizing does, because that's in essence what you're doing when you do that, and even if they were to read a paragraph or two, they will typically tell you it's interesting but doesn't apply to their oh so unique situation.
Secondly, then they get to read that you're doing 180s and whatnot because that's what the book instructs on, and may therefore look at your "changes" as purely manipulative and not real.
Bottom line is that this is "pursuing" type behavior, and that very often just pushes them further away, giving them another reason to.
The reason underlying why you wish to do so is because you think the book is good and makes sense, so you believe they'll get the same sense of things. But they're into a different book, so to speak. Understand their mind set, for there is where the "coming out of the fog" has to occur.
