Hi and welcome.
Your situation sounds difficult to say the least. My first question for you is what do you want? Do you want to stay in your relationship? That will drive a lot of the decisions you have to make. We can support you and try to help you navigate your way through your situation regardless though. You do not have to deal with this alone anymore.
Is your husband in therapy by any chance? Can I ask what happened when he tried to commit suicide? did he go to the hospital?
I apologize for all of the questions here. I am trying to get a better feel for how to help and support you even though many of my questions are about your husband.

I am glad you reached out for help and support here. That takes a lot of courage and I can hear the pain in the words you wrote.
Share more when you can.
