I don't know too much about PM, or how to rephrase things so that they will come out right for you. I don't know your situation, I don't really know what you want or what you are willing to sacrifice.
But it seems to me that if you can find the courage and the strength to stand up for yourself and what you want, maybe you will be OK. You won't get what you want, not right away, maybe not at all. But you will feel better about yourself. And your husband might listen.
I think it is a good idea to write things down, because the process will make your thoughts clear and concise. But I wouldn't write him a letter. It's difficult to talk about these things because you know there is likely to be some sort of negative reaction. But I think you should tell him to his face, looking him straight in the eye. That way he can see your strength and resolve. He will know you aren't fooling around.
Are you really ready to walk? A lot of people (present company included) throw around the D word without being serious, which I think just undermines your position. On the other hand, I think a one month deadline might not be enough time for any realistic chance for change.
Welcome to the forum. I salute your courage and wish you good luck .
