Parents still friendly with abuser

My parents are still friendly with my cousin who sexually abused me when I was a young kid, about 4 or 5. It feels like they do not care how it affects me anymore or that I am just now working through the pain that it has caused me over the years. It comes to me in waves about what happened to me, and when they talk with the wife of the abuser, I get a wave of what happened, and then I feel like I might shut down. I also can not talk to my parents about it, as they bring it back to things that they have experienced and not about what I am trying to tell them, which is not helpful in any way.
