I would simply go home. I would not even tell him, I would just do it. If he wants out of the marriage, let him move out. It is your house too, unless it is in his name only, so you are free to live there. If you wait, that may not be the case-depending on your state's laws.
I do not know exactly how he is preventing you from doing a 180. You do have to speak with him about certain things, but that should not prevent you from doing a 180. I do not know if there are other factors that you may have left out, but nothing should prevent you from doing it. Do not let your husband take all the power in the relationship. You can do it!!
