Honestly, redbud, from what you have described, I doubt that guardianship will be granted or that involuntary inpatient commitment is going to be ordered by the court at this time given the circumstances. Unfortunately, just as in child protection cases, it takes a lot of injury or risk of injury to provide sufficient evidence to reach the standard burden of proof. You may "feel" afraid but unless he actually does something (like swinging a bat or walking around with a knife in his hand) to show he is a danger to you or himself, then the case is weak.
Hang in there. I'm praying for you.
