Oh boy, can I relate. Looking back now I have some sound advise that I wish I had heard. First thing is break the silence to your family and friends, even if they are distant. You need evidence on his unusual behaviour and it is his insecurity that is most dangerous to you because you don't know how deep that goes. Your silence is his advantage. If he threatens you in ANY way, make a report to the police. (eg, "I will never let you go" is a serious threat) Go to a marraige counsellor and use that person as a mediator to express your real intentions (another witness and support for you).

As for the money, you would be surprised and amazed at how resourseful you can be with little money. Don't use that as an excuse. You will find your way through that with the support of friends or societies that are out there just for people like you. Low money is only temporary.

Also, when you tell him you are leaving, do not leave yourself alone with him.

I was imprisioned for a year and a half and when I did go out, I was stalked and questioned extensively when I returned. My ex's insecurity was so deep that he was willing and able to kill me, possibly the kids, and certainly himself after he did the deed. I knew if I left, I would be dead. I finally got help through a counsellor, who insisted we go on antidepressants before she tried to get us back together. (She could see the danger to me). Then I broke down and told my doctor what was going on and he put me on light antidepressants and put him on a cocktail of antipsycotic drugs. This gave me the advantage I needed to escape with my kids.

Your situation may not be this bad, but I couldn't tell that mine would be this bad, and it doesnt' hurt to be prepared.
