Well, it's too late to ask "What are your goals in life?" and "What tasks do you want to share while married? What tasks do you want to do? What tasks do you want me to do?" Then, you could have bailed out.
So now, you need to have a talk. It might be interrogative, but you need to get real answers. "What kind of job are you looking for?" "Where do you see yourself career-wise in five years?" "How do you expect to get to that goal?" Basically, you need to unearth the truth. Is she motivated to grow her career or is she just looking for a fun job but if it isn't there, she is okay with sitting at home and riding your gravy train while watching soap ops on TV.
You are the man. You need to get answers, bare minimum. You can't change people. They have to be self-motivated. Sucks but that's the truth.
