Nero, listen, this tough is freakin hard. No two ways about it. So, nothing wrong with you putting your feelings down to people who understand exactly what you are going through.
I am soooo happy you have turned over that stuff to your sister. I know you are worried about your mother's finances, but, its not someone else's worry, right?
I am sorry your h answered the way he did. Dont you just want to smack them off the side of the head sometimes?
You are doing wonderfully, my friend. I see changes in you. I am so glad of it.
You will know when you are ready whether it is time to do something different.
