The man incapacitated you, violated you, and traumatized you... you have every right to be scared of him. What you are describing is hypervigilance, quite common in PTSD. Spiritofnow wrote about it recently in another thread:

If you want to write about your experiences we have a diaries section that is less public. I have found that writing about the trauma helps. There are plenty of us here who have been there too, and the more you write the more opportunities we have to help. Don't be afraid to ask questions either...
