I feel for this person. I recently had a stalker over the summer, a family friend whom I met at my sister's wedding. He had some sort of break down, declared me to be his lover, received my email via unwitting family members. Luckily someone had raised the alarm. Said stalked flew out of state fully expecting to find me and be with me. It did not happen, but I certainly was preparing for an altercation and was traumatized by every unexpected knock or ring at the door.
