You dont have to. The final argument between my mother and I was on my daughters 16th birthday. In November she turns 23 and the entire family is better off for not having to deal with her manipulation and simple nastiness as a human. If you're here... on this site... simplicity is key to your own wellbeing. Blood may be thicker than water, but who cares if only one person is bleeding. Just the opinion of a 45 year old whose been on his own since 17. Good luck!
