My parents won't attend my wedding?

My parents told me they will not be attending my wedding because they disapprove of my fiance Kagney. They despise her because when i first met her she was a stripper. However once we started dating she gave it up because i wasn't comfortable with it. They also hate her because she has a son from a previous relationship and they think she is a slut because she had a child out of wedlock. She got tested for STD's to prove to them she didn't have a STD. She has done everything in her power to get my parents to see is an amazing women who i love and want to marry. It really hurts me they won't show up just because of her. What should i do?
