You are in a really tough spot. I know that it is very difficult to try to explain things to other people for a whole host of reasons. The people here are great about understanding as they have been where you are.
You say that he is your soon to be ex husband. Has the divorce been filed? Where are you at in the process? How long have you been together? Do you have any kids?
There is a leaving board for people that are on their way out of the relationship or have already left. There are lessons on that board that will help you with leaving.
There is also a legal board for those that have questions about the legalities of it all.
Welcome, you have found a place where you can get help and support. Start sharing as much of your story as you are comfortable with and I am sure that others will chime in to offer whatever they can.
