O.K. I need help in my plight.
I'm 16 and I was going out with this boy for about 2 months and we never even kissed so I wouldn't say it got serious at all.The main problem is, is that we both go to the same boarding school and he's in some of my classes so I have to see him quite a lot of the time. It was quite sweet over the summer but then he began to get quite creepy once we got back to school in september ( following me around, coming to my window at night and other things like that which were mainly annoying but also had a hint of strangeness to them like getting annoyed at me for not eating breakfast with him.) so I broke it off. he was really upset and we didn't talk for about 2 weeks though many emails were sent by him, quite mean emails. He gave me the gifts I got him back, even the t-shirt I made him and said he never wanted to speak to me again. I was O.K with this since I expected it though it did hurt a little.
Now, he's started writing poetry, quite harsh poetry in latin and showing it to my Latin teachers. He's sent emails to my friends asking them to help win me back for him and one to my sister asking her to go through my stuff for him. He even shaved his head in anger because I said once that long hair suited him and according to my friend tried to send some of it to me (!)
I need some help of what to do. I made it quite plain that the ball was in his court and I would accept him being angry at me but this is far too far.
What can I do to make him realise that he needs to leave me alone
