If you really think he would take a gun to work and is known to be a hothead who would come over and blast away at your family or at work, then no.
As for your other actions, Why did you want a man to be with you only because you threatened him with work exposure?
Remove the threats to your WH and his job. Tell him he can do what he wants. If he stays, then that's true reconciliation. It's not true reconciliation if he's there only from coercion.
If he wants to stay, then you'll have a true reconciliation and happier marriage if he's not mentally doing what that song lyric says - counting the days until the end of time or until one or the other of you dies so he can be free.
If he's hanging around after the threat to tell is taken off the table and he knows it will never happen, then you'll know he's with you because he wants to be with you.,
