How do I deal with my marriage that is no longer happy?

My husband and I have been married for 17 years. Somehow, somewhere in the early years we gradually stopped being friends and became wary of each other. There has been verbal abuse through the years. Presently, we don't communicate consistently, there is no friendship between us where we can talk about anything. If ever we talk, its about the kids. We are basically living together for our kids. Our conversations never expand to something we are both interested in. Its either a yes or a no answer, a nod or just no response at all. I don't know anymore what to do. We've gone to counseling but somehow its goes back to where we started. What do I do now?
