I seem to have spread confusion. Let me try again.

I have a friend of long standing. He has had many troubles. He never tried to commit suicide.

Then he got involved with a woman who regularly tried (how hard I cannot say) to do so. That was the only period during which he tried to commit suicide. The only times he did so was when she did so. Even then he did not do so every time she did so.

This suggests it is safer to keep a fair distance from those who do try to commit suicide. If they lock you into their lives you may find you go with them.
