Up until recently my father and step mother were getting a divorce, they recently changed their minds for "financial reasons." I hate my step mother. She made my high school years hell. She told my entire family I lost my virginity at 15 which I didn't, but even if I had, why tell them? and that I was the biggest whore in my school. She also did everything she could to try to ruin my brothers wedding last year. She stormed out of the ceremony because she didn't get special flowers, didn't let my dad be in any pictures, and told everyone I had only gotten engaged because I was pregnant which I wasn't. So my question is... Can I not invite her to my wedding? And how do I talk to my dad about this? I'm not getting married until June 2014, but I want to figure this out now so my dad isn't blind sided closer to the big day.
