I hope Aggie's Intimacy Challenge is going well. Here are excerpts of a case study of a fellow who found intimacy so stressful, he attempted suicide:
Like a Fish Needs a Bicycle: For Some People, Intimacy Is Toxic by Richard a. Friedman, M.D
...
Everything seemed to be going well until, one day, the father got a call from his son’s girlfriend. She had not heard from the son for several days, so she went to his apartment and found him semiconscious in a pool of blood. He had taken an overdose of sleeping pills and slit his wrists.
After a brief hospitalization, where he was treated for depression with medication, he returned home and broke off the relationship. Soon after, he moved to Europe to work but remained in frequent e-mail contact with his family. His messages were always pleasant, though businesslike, full of the day-to-day details of his life. The only thing missing, his father recalled, was any sense
of feeling....
And then I suddenly understood. He wasn’t depressed or unhappy at all. He enjoyed his work as a software engineer immensely, and he was obviously successful at it. It was just that human relationships were not that important to him; in fact, he found them stressfull.

I had a hard time explaining all this to the patient’s father. Finally, I came up with an analogy that I had some hesitation about, but since I discovered that both of us were dog lovers, I gave it a try. I explained that some breeds, like Labradors, are extremely affiliative; other breeds are more aloof and will squirm if you try to hold them.
