Background -- 18 year old guy, just started uni, currently single. A couple of years ago in high-school, a girl in my class (1 year older than me) managed to find out what my e-mail was, and she started sending me e-mails, trying to create conversation with me. That we did; we talked for quite a long time. It was obvious that she was attracted to me (heck, I have proof of it, with the 2000+ e-mails she sent). Initially she seemed nice, so I agreed to go out with her (over e-mail). But then she started acting in a pretty suffocating, clingy manner -- sending close to a hundred e-mails/texts per day, telling me that she wanted to live with me forever, that she wouldn't be able to cope if I died, among other creepy things. Of course, we hadn't even dated yet, nor had I even told her whether or not I had any intention of being in a relationship with her. I didn't respond to her for about 24 hours because I had just got sick of her. As a result, she started ranting about what a bad boyfriend I would be, and other words to that effect (which I found a little irritating, especially given that I had no intention of being with her), so we agreed that we should scrap the dating idea, and instead opt to 'just be friends'. That didn't last very long. Within a week she was offering intimacy/sex, telling me that she'd do anything to be with me. I declined, mostly because she really made me uncomfortable, and I had no idea how a meeting with her would go. So, I cut contact again. A few weeks later, she told me she needed help, that she was going crazy -- but she didn't want to talk about it. So I figured that there wasn't much harm in simply talking to her as a friend: she had just started uni, so I imagined that she might be feeling a bit lonely. Shockingly, she was the one who stopped talking to me after a while. A month later, at school, I saw her standing on her own (she was supposed to be at uni) -- she told me she was going to a mental hospital, and walked away before I could say anything. Fast forward about a year. I receive an e-mail from her, which says something along the lines of "Hi. It's been 417 days since I talked to you. How have you been?" I'm not sure what to do at this point. On the one hand, if I cut contact with her or blocked her e-mails, I could spare myself a lot of trouble. On the other hand, if I did respond, she could start becoming attached again (her younger brother had told me that she'd restarted her first year at uni), OR it might help her relax at uni a little if she at least has one person she can talk to. Do you think the best course of action would be to cut contact with her? EDIT: Just to clarify, this girl and the girl I mentioned in the Flirty girl turned out to be a lesbian thread are not the same person.
