I only made half way through this. While what he says certainly happens, what he's missing is the rest of us
. His "25 years experience" only applies to dysfunctional marriages. The relationships that work don't need his "services". So, all he can tell you is how BAD marriages operate. What he has no experience with is how GOOD marriages operate. (unless he himself is in a functional marriage -- though, it doesn't sound likely)
I seem to make it onto several groups promoting Christ-centered marriage ... probably because the interested parties overlap quite a bit with the homeschooling communities that I intend to follow. Anyhow, these people have a lot of good advice about building up and keeping a good marriage because they're LIVING what they talk about. They're married and have been for decades. They talk about what WORKS, not about what doesn't work. Their only major downside is a little Protestant spin, but if you can handle this guy, their touch of Protestantism isn't going to hurt you. Some of them are even Catholic. A quick Google search and I'm sure you'll find dozens of such sites.
This guy has seen too much failure -- in his own life or others, who knows. What you need to succeed is to hear from those who've been successful, not those who haven't.
