I have been conflicted by this since the day I told my dad and step mom that I was pregnant.
My step mother and I have a very unhealthy relationship. It has been civil for the last 7 years (since my first half sister was born). To put it short, my dad and step mom have been together for 9 years. My mom and dad have been divorced for only 7 years. And my step mom used to be my mom's best friend.
My step mother was very excited when I told her the news and I appreciate it. However to me she has always been Kathy, I don't usual address her as my step mother but as my dad's wife. So the thought of my child calling her grandma makes me ill.
How do I tell her this? Or am I being irrational?
