You are doing the right thing. Sorry your success was temporary. If what you say is true than maybe you could suggest a Christian theripist.
These are sympathy ploys (though the suicidal threats are to be taken seriously) it is an attempt to control the situation.
If he is a bad person (we all are to some degree) then what is he doing about it? What is causing him to think he is so bad? Looking at yourself the ugly mirror is a scary thing however that actually is the easy part. Real work is afterwards.
You are doing well.
