I really wish he would leave me alone. We've been on/off since March. Every time I walk away, he comes back within a few days. If I ignore his texts, he shows up at my job or manages to "accidentally" bump into me somewhere. He'll claim it's because he misses spending time with me but as soon as I tell him I want nothing to do with him, he starts insulting me. Yesterday, he told me he was getting a kick out of manipulating an "adult woman" (I'm 22, he's 18) and that the only reason he always comes back is because I'm entertainment on a rainy day. He kept blaming his behaviour on the fact that he has Tourette's but I'm not even sure I believe it anymore... I don't think he was diagnosed with anything. He's ill but he'll never get help because he truly believes he's just fine the way he is.
