He also sounded as if he was very tense. He had the very frequent stomach aches, which sometimes are a sign of depression, but sometimes can also come from antidepressant treatments. And I'm not sure what treatment he was having, and overall, you got the impression of a boy who was suffering a great deal of psychological pain, who was depressed and cut off from other people, except for her. But he did make reference to the fact that she had had the courage to try suicide before. I can't really judge the relationship just from the letters from one side.
Suicide pacts are very unusual in young people.
In the study we did in New York, there was only one suicide pact out of 140 suicides. They are most common in elderly couples, who often have been married to each other for many, many years, where they can't imagine life without each other. They often occur when one partner is physically ill and is going to die, and they both decide to commit suicide, rather than wait for that. But they are unusual in this age. When they do occur, there is almost always some romantic relationship between the partners, and you don't necessarily get the picture of one very dominating partner and one partner who just will go along with whatever they say.
