Moving on from abuive relationship

Hey guys. So about a year ago I got out of a very manipulative and controlling/ threatening relationship. Honestly the only reason I was able to get out of it was when I got the police involved. Like I said this was a year ago. I’ve been thinking of starting to date again, however normally at some point in dating, the conversation comes up about past relationships and how it went down and everything.

Does anyone have any advice on how to handle that? Honestly I’ve moved on and I’m ready to date, but at the same time I’d rather not go into every little AWEFUL detail of my past relationship. I don’t want any potential dates to think I’m crazy because of the situation I was in. (I’m always wary of people who call their ex’s crazy, but in my situation it’s clinically true.) I don’t want to under-share either because then it will seem like I’m not being honest about it either. Does anyone have any advice?
