Maybe the word you are seeking is "passive" instead of "nice". There is a big difference. If you have taken a back seat to the decisions or if you agreed with whatever made her happy....just to keep the peace, then that is being passive. Some men get to a point in the M that they just turn everyting over to the W and they're fine with her running the ship. But, then he doesn't understand when the R starts to fall apart.
A passive man is not attractive, IMO. It's also MHO that women don't want the H to take the lazy way out and just let her raise the kids, run the home, and any other important decision making efforts that come along. She will lose respect for a knot on the log, let me tell you. There have been so many H's to come here and say that the W doesn't want to ML anymore and isn't attracted, etc. She can't if she doesn't respect him as a man.
Don't lose that respect.
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!
