He will do what he must do when he must do it. Once he has made his passage he will not be the same. He is at a major turning point in his life, a normal part of the male maturing process that, should he be successful in navigating through the storms, will help him to lead a fuller and more satisfying life, accepting the normal limitations inherent with the aging process. Some men aren't successful in the passage. Suicide rates increase for men as they age.
Suicide offers the promise of release from seemingly unbearable emotional pain.
For some, suicide is the only way to suppress the emotional pain associated with the midlife passage. You need to be aware of what's happening to your man. Being aware will make you less apt to blame yourself for the things going wrong. He will be blaming you as it is, because he knows he's not wrong. There's not much you can do to speed up his passage through this crisis in your lives.
