I'm going to leave my husband stranded at the gas station in an ice storm
Why would you want to do that to your husband?
I no longer want to be committed to my marriage.
Facing problems in your marriage is to be expected, but you should resolve your differences in productive ways. It's rude and cruel to leave someone stranded anywhere. Leaving him in an ice storm can cause hypothermia, which you will be responsible for.
He's a bastard that deserves what's coming to him.
That may be true, but you are still in the wrong for leaving him in a life threatening situation. If he dies, you'd be rightly responsible for it.
