Dear C.,
Is it possible that your husband doesn't believe your "change of heart"? You have not been interested in him as a man you say and now you are scared to death and need him for a while. I think you should be honest with yourself about this because if you are, then you can still work out an arrangement that is good for you and your babies, where you can raise them in a not so destructive environment (maybe even with his willing help). When you are right with yourself, God will show you the answers, but when you are fearful and manipulating a "solution", it tends to turn out wrong because you are clinging to the same old (bad) habits that got you here to begin with.
Good luck,
N.
