And Fen: A little late, but yes. Dumb him clearly. Clingy guys are scary.
I had (for a very short time) a boyfriend in college that started showing up outside my classes when he knew I had a bit of free time. And then he'd stay with me until I had class. Lather, rinse, repeat. And at night, he'd come and study with me. Or go wherever I was going in the evenings.
Basically, if I had free time, he thought I should be with him. Luckily, I was living in a Catholic special interest house, so I could, in fact, kick him out at night. And did.
I felt like I had a freaking stalker. I dumped him pretty much by telling him that he was freaking me with his stalker behavior and that I needed alone time for me. And, you know, to hang out with other people that weren't him.
