I'm the same way with my wife. Sometimes it is just so fun to drive her crazy. One day she might actually call my bluff and leave me though! I think the most recent horror item I willingly watched of my own volition was American Horror Story though I stopped watching around the sixth season or so. Those first two or three seasons were pretty fantastic. I don't remember An American Werewolf in London, but back in the day there was a scary Disney movie called The Watcher in the Woods. That thing terrified me. Turned out it was more mystery/science fiction than horror, but it was still pretty unnerving.
