Only your husband can say what his reasons were. But I think it is fairly common for family members to be desensitized and it's easy for them to minimize and hard to tell when it's really serious. Maybe he didn't understand the danger you were in. Anger can play a part too. Mine has not been into getting treatment or dealing with a crisis either - but I also wouldn't admit when I was suicidal. He doesn't understand what I experienced, and at the time I wasn't able to tell him. Once I was advised to go to the ER for self-inflicted injuries, and I said I didn't want to because I was too tired. He responded by yelling, "You're tired! I'm the one who is tired with everything you put me through!" (don't remember exact words now, but something like that). There were other times he went out of town and left me when I was suicidal, but I had told him to go and that he didn't need to stay. I wasn't going to tell him what my plans were, because I didn't want him around to stop me, but I thought it was fairly obvious. Maybe it wasn't as obvious as I thought, though.

Sometimes they do just get tired of it. But whatever the reason, it is still negligent not to get treatment to someone who is in a life or death situation.
