my stalker

We had several dates in August. Regular boring dates. Nothing special. The guy was boring. Well, I can't tell that he was a bad guy. No, not at all. 28 y.o. Hardworking. His own company. Nice car. Two cars actually. But it happend that I was not interested and after 2 dates or so I told him that I did not see any point to continue the development of our relationships. I expressed my thoughts very nicely, actually I told him "thank you" and wished him to find a new girl who will love him.
I did not know that it was only beginning of the story. He started to call me many times a day, park his car near my house and try to contact me anyway. He called me several times a day. I could not even text to my friends because of his calls. The battery was down all the time, I charged my phone every day. I told him that if he called or contacted me in the street I would call the police. He started to hide his number during the calls.
Two times during that period my I switched my phone off for a month or so. But as soon I turned it on in several hours I noticed missed calls from him.
On Wedesday I accidentially picked up the phone.
"Hello, my love. How are you? Did you miss me?"
"Who are you?"
" Oh, you don't know! That's me!"
"Me is here, but who are you? I have no recollections..."
" That's me, your pain in the neck, that's what you are thinking about me!"
At that moment I felt so sorry for him, poor guy who can't control his feelings. Poor guy who is ready to do everything to make me be with him. How desperate and pathetic he is.
He called me when I was in Hoboken, when I came to Bayonne he met me at the train station.
I asked himseveral questions, I told him that I used to feel the same several years ago. I tried to convince him that the best for him is to forget about me and find a girl with whom he will have mutial feelings. I found out that he has not dated anybody since I broke up with him (if I can use this word, we were not a couple).
That guy is sick, he is obsesssed with me. I told him that I sleep with other guys, he proposed to me. I told  him to give me money, he asked how much I need. I asked him to leave me alone, he begged me to think about it. He told me that he could not control his emotions and sometimes he was waslking aroung the phone hours thinking if he sould call me.
He offered me to do different activities together. He asked me to dance together and watch movies, have dinners and go to the beach. He behaved as we were a couple, which got some issues and wants to work over them. I realized that he was so crazy, obessed and insecure. I noticed that he stopped feeling the reality and listening to me.
I regret that I talked to him.....I was hoping that I will convince him to leave me, but I gave him new hopes and he doubled his efforts.
That night I got a nightmare. It is not fun, I am scared.
