*Trigger warning* Boyfriend* asked if he could fantasize about me being a child and I’m horrified

Hey guys I’m really shook up right now and need some advice, so please be gentle. I’m 22F and I have a 25M boyfriend of around 6 months. He told me that his biggest fantasy is to have sex with a little girl (under 12) because of something that happened to him as a child. I don’t know how to handle this and am scared he’ll act on it. I’ve heard too many horror stories about this. I don’t know what to think or how to handle my feelings. He’s otherwise a great boyfriend. Help!<br><br>Edit: I’ve read all the comments and I just want to say thank you so much for all the helpful advice and support. I really appreciate all the help and I will definitely be ending things.
