I told the doctors I would do whatever it takes for my husband to get sick and die.
Have you already done something to your husband?
No, I'm just tired of seeing him be alive. I've done what I was supposed to do. Now it's his turn to do what he was supposed to do
Marriage is hard but you cannot want your spouse dead. And if you do something to hasten their death, it is even worse since you will go to prison. It is better to divorce them instead.
I just want him gone.
Then file for divorce and move away. Wishing someone dead is pathological. Hire an attorney.
