My take -

1 If someone calling a crisis line said suicide is always an option that would worry me. The worker should have asked more questions about what does that mean to you.

2 I think it was a good idea that the police brought your husband because your husband knows your normal and would recognize a crisis or unusual behavior (or so we would hope)

3 You said you were fine. I presume your husband felt you didn't need help. He could certainly have been helpful but he can't read your mind. If you ask him for help does he comply?

Sounds like a very confusing situation all the way around.

So how are you feeling NOW?
