I have been on and off Psychcentral for quite some time. This rough relationship dynamic, whether between yourself and family, or yourself and husband, seems to be a common pattern. I am not blaming you by any means, but it seems like you try to keep relationships going that are very much not working.

I know this sounds very simplified, but have you considered doing a pros/cons list? Something like "Pros/Cons of trying to maintain these relationships". I find if I'm struggling with a tough decision, these types of lists can help.

I know this is a one-sided account of things, but from what you have described, your mother and sisters do not strike me as individuals that I would want to have relationships with.
