Molested as a child.

I was about 7-8 years old when I was molested by my moms brother. I don’t refer to him as my uncle because of what he did to me. I am 25 now. No kids and soon to be married. I have never told anyone except one boyfriend when I was in middle school. My fiancé doesn’t know and it’s so hard for me to tell him, I’m afraid he may see me different. I want to tell him before the wedding. It haunts me everyday. & has been crossing my mind more often than ever before....
