I don't know how it factors in to your book, but I agree with Rob on the weakness thing. Yes, on (rare) occasion, it is nice to see some vulnerability from your man. Like, when my h's grandfather died, he cried like a baby. Because that man was his role model/mentor...in fact he has commented a time or two that his grandfather would be immensely disappointed in his actions of late, but I digress--
In certain situations, that is fine. But give me a sweaty guy in dirty jeans and workboots over a metrosexual in a turtleneck sweater with a fresh manicure....
Big picture, I think that men should not be afraid to step up and be leaders in their families. Not in an obnoxious egotistical "I Tarzan, you Jane" way. But in a "this family means the world to me and I will step up to protect/defend/provide for us no matter what" kind of way. It is NOT attractive to think your Husband has no plan/goal/vision for the future of his family, nor a clue how to make the vision reality...
