My very good friend started her own business six months ago with another friend. Our friendship is now gone.

When the two went into business, my friend said that the other relationship was just a "partnership" but now it seems that those two are inseprable. Business partnership has become a 24/7 relationship...dinner, shopping, travel, all of it.....while my friend as left me and even her family on the back burner. Who should speak up? Me? Her family? No one?
