Welcome to pc forums. Sorry to hear about what you went through and what you are going through now. Now, personally I think you should do whatever you believe is right. You are not doing anything wrong if you explain to someone about how you feel - And naturally as humans we do need to express ourselves to get things off our backs. Don't let him say you did anything wrong because you are simply expressing yourself and nothing more. As for telling everybody and him, you should think about what words to say carefully. I have had an experience with people for that kind of thing, and trust me when I say that if you say words the wrong way, it sometimes may not end well. But the truth is the truth. If you are going to speak, make sure you have nothing but the truth about your feelings and what he did.

Oh, and remember if you need some people to talk to get through a rough time, plenty of people including myself are able to speak to you here on the pc forums. Just an option but just in case you ever did want to speak to someone.

I wish you nothing but good luck for the times to come.
