Thank you for writing to JustAnswer with your question.
I am sorry to hear of your situation. There does seem to be a very deep problem here, that he won't allow you to call him for such reasonsas you describe is not usual. You ask "is my marriage save able". This depends not only on you, but also on your husband. It definately takes two working at a marriage, and only one person invested will only have sorrow from the situation.
First of all, you need to take care of yourself. Start counseling and become empowered in who you are and know your self worth.
You can ask your husband if he is willing to work in couples therapy. If he is not willing to do this then he is not willing to look at himself and put in any effort towards this marriage. Again, marriage takes effort. If he is not willing to change then you must move forward because you are worth having a person who is as willing as you to work as a team.
I'd recommend you take a look at this link which gives information and help regarding relationships (go to the tab on the left and click relationships to read the section that you are interested in - there is information on health relationships as well as dealing with a break-up) http://www.helpguide.org/
I wish you the best. If you have questions or comments still needing to be addressed feel free to reply so that I may respond.
