Being forced to wear a scarlet letter

I am devastated that at 31 years old my parents are treating my pregnancy like a huge disappointment because my fiancé and I aren't married yet. While the rest of the family (his side) are supportive and happy for us, my parents are forcing me to wear a scarlet letter! I'm irrevocably crushed by the fact that they report to me about the church members that they have had slanderous conversations about me with, and how utterly disappointed all of them are. How could I be sooooo disrespectful to my parents?... Seriously?! I'm appalled at how hypocritical they are as well as how unchristian their behavior is and their dragging other "Christians" into their judgemental ways. I'm 31... Not 16. And I certainly don't feel I deserve to wear this scarlet letter.
