How do I know if I'm ready to date again?

I went on a date for the first time since getting out of a 5 1/2 year relationship. I was sexually assaulted on the date and forced to give the guy a blow job at knife point. I was able to distract him enough to punch him in the throat and get free. I am talking to a guy now who is very handsome and seems great, but how do I know if I am ready to meet him or go on a date? I'm still kind of scared. Please help!
