I don't believe in the "disposable" word. Your family never can be disposable. One thing is you have troubles with all the members of your family and other is disposable'em.
Maybe you need to talk with'em and fix all the problems talking. Or you can go away and search for a new single life. It's your choice. But always keep on mind this: the family is the first thing for a happy life. And in one moment of your future you made one too.
Ehh, i'm happy with my family too! They have the most important thing on my life.
