My friend met this guy and dated for a couple of years. She'd wanted to break up with him for the last half of it, but never could do it. She became increasingly convinced of what all her friends knew, that he was crazy. I made an amateur diagnosis of manifest paranoid schizophrenia. Another smart friend did too. And we later found out that he'd been discharged from the marines for it - he managed to pay his way into an honorable discharge by shopping for private shrinks long enough for his term to expire. She dumped him, then immediately started dating another friend (yeah, that's her problem). He refuses to recognize that they're not dating. He was finally kicked out of the house she lives in (it's my house, but my involvement with this situation is tangential), but he still comes by regularly, calls her daily, and makes plans that he expects her to share in. For example, he bought concert tickets for her, and assumed they would be spending her birthday together. I think she's leading him on more than she understands, simply by having any sort of communication with him. She says she feels sorry for him, and that he has no friends (which is true, he's alienated everyone in his life - not even his family cares for him). I have a sneaking suspicion that she's not telling the whole story to her current boyfriend and I, and that he's getting more encouragement than she lets on to. What I would really like is some advice in how to convince her to cut off all contact with him. He's made threats, and I really don't want to see her kidnapped, killed, or whatever. She's convinced that he wasn't serious. I don't even sleep without a gun within reach.
