Husband's Mental Health

I just don't know what to do anymore. My husband has struggled with mental health issues in the past. He was doing so good for so long. The last few months have been rough. Every night he talks about wanting to leave to jump off a local bridge. And every night I talk him down and he ends up going to bed. He won't see a therapist after a bad experience with one. And he has been in the mental hospital twice and has said how it never helped him. This morning he left for work (we leave at the same time) and instead if going to work is just aimlessly driving around. I talked on the phone to him but he ended up get mad and hanging up.

I know I need to be there for him, and I love him more than anything. But this is taking a toll on my mental health. I'm exhausted. I don't look forward to going home in the evenings. Since he started this recent decline it feels like there is always tension. We are never in the good place we were before.
