I think it's very important to sort this out in couples counseling. A good couples counselor will help you to take a look at the whole picture, to discover issues/potential remedies TOGETHER.
This might also involve each of you getting involved in various support groups, as well.
First, I'd see a couples counselor to set some goals together and to make sure you are on the same page. It's too easy to increase the gap between the two of you and to start heading in very different directions.
Just my two cents.
