How do you stop the thoughts from flooding in after an abusive relationship?

Like prior to this I had never dated and this girl was physically abusive she would haul off and hit me in the head if she was losing in a game we were playing. Another time she hit me because I had a slow reaction to our dog doing something. I was bending over one time to pet our dog and she hauled off and kneed me in the ass. She also hit, kicked and slammed our dog he has a massive dent in his crate that I look at everyday as a reminder of what she did to him. Anyways she was supposed to be a good person and but on a nice person act to the world so they never seen this side. How do I stop the thoughts that what’s stopping the next girl if I find another one being like this pretending to be nice then abusive later on.
