I agree with anti on this one.
Although I have no children, I've been through this myself.
As far as counseling goes, it only works if both of you are willing to go. In my case, the wife wanted nothing to do with it.
It was only after I gave up, and agreed to a divorce that she finally decided a divorce was not what she wanted. But that was my case, not yours.
The end result was that I realized the business I was trying to build at the time was taking a higher priority over my marriage, although I was doing it for the both of us. The problem was that I was forcing her to be a part of it when she wanted nothing to do with it. ...and I was ignoring her needs.
Today, I make sure my wife comes first. I started a new business and the wife has nothing to do with it. Should she chose to become a part of it, the door is open to her.
If anything, get some advice from someone you trust. A minister or a marriage counseler. Even if your wife doesn't go with you. It might shed some light as to what your faults may be, if there are any. If she refuses to get counseling with you at first, she may change her mind if she sees you making the effort to get help by yourself.
Best quote I've heard about marriage?
"Getting married is like reaching the Promised Land. It takes a lot of work to harvest all that milk and honey."
