Did she control your life & decisions growing up & you were compliant with that? It's hard to change mind sets without making waves at some point in time.
Ugh, I was an only child & I remember my mom saying you will be my baby all your life. I remember thinking not only NO, but #@[[ NO. We fought all my life because I was fighting that concept. Things got better the older I got maybe because she got tired of fighting my seriously independent nature. She would get mad at things & not call for a couple of weeks but let her sort it out on her own.
Lol....Training one's parent is always more difficult the older they get
