I have been luking for a few weeks and I would like to throw my hat in here and see if I can get some help and ideas to save my marriage.

Married 17 years, 2 kids 11 and 9. I am 41 and my W is also 41. I have the divorce busting book and I am on my second read. I think I am dealing with a Midlife Crisis. I know I am partially to blame for where we are. I have a hard time communicating and this has pushed her away to the point that she is saying. "i know longer love you, I feel no connection to you and I am not sure I want to reapir the marriage".
I have been giving her space but my workaholic history and poor communication makes it hard for me to logically give her space. I want to show her I am matured and can be present and a better participant in the marriage and family. I am working HARD on myself. Learning to not push her (though I have backslides at times).
I need help figuring out what actions I need to take that will make a difference. Giviing space seems to be more of the same instead a real 180 but being home and more helpful around the house with the kids is met with great resistance.
Help!
