<human>: Could you distill the essence of the text into 1-3 sentences?

This guy, let's call him John, and I have been "talking" for about a month and we've hooked up twice but I called it off for a little bit because I didn't know how I felt. During this time, I went to a party and was sexually assaulted by someone else (not going to go into detail).

Now, John wants to start things up again and part of me wants to too, but now I have this huge obstacle of recovering from my trauma. I don't want to freak him out with this because it's a big thing and we are extremely casual. 

Any advice on whether I should tell him/how much I should tell him? Or is this just a bad idea and should I just call it off for a while...?
<bot>: was hooking up w this guy, then i stopped it for a little. was raped at a party, now idk how to proceed with the initial guy.
