I can't tell you whether you are doing the right thing or not. Each individual here has their own basis of experience and they don't know enough about your situation to tell you whether you are making the right decision.
My AS has threatened suicide so many times I can't even begin to count. When I've known where he was, I called the police. When I didn't know where he was, I braced myself. And there have been times when I've swooped in and rescued him. This has been going on for about 15 years but escalated in the last five or six years.
I've realized that I simply can't handle this. I've let go and he is in the hands of his HP. That is how I've had to deal with it but that is me and my situation. We all do what our mother's hearts can handle at any given time. I pray a lot.
I'm so sorry that you are dealing with this. It is very hard.
