hellobritty,
You said in another post that you "just don't want to be married anymore," and if the "situation can't continue," then you are nearly ready to take the next step, and accept that what you wish were not real is indeed "very real." You already know this, of course, having lived it for the last year (I hope I remember this correctly from your post elsewhere).
Even if you are not ready to take the final step and say "I want a divorce," it is wise to go to a lawyer to see about your options, because you need to be prepared for that in case your husband does something that makes the necessity something that has to be acted on quickly. Think of it as preparing an emergency or contingency plan.
Knowing what your rights are under the law and the likely options you would have gives back to you some control in a situation that feels out of control and is being driven by your husband and his changes rather than your wishes. Knowledge is power, and seeing a lawyer provides you with knowledge that can help you plan. You have a daughter to protect, so if you find it difficult to act on your own behalf, act on hers.
My husband did the same to me, out of the proverbial blue, after 32 years of marriage. It took me three years to call it quits, and I've been living on my own for three years now. It was hard, and painful, but my life is so much more peaceful now.
