Maybe a lifetime movie? Not sure...?

I am looking for a movie, i want to say it was aired on Lifetime channel. A woman goes to jail for the murder of her husband and while she is in jail, she finds out that her husband is still alive. At the end of the movie, she really does kill him because they cant get her again for the same crime. I know there is one like it with Ashley Judd called Double Jeopardy but I dont think that is the one I am looking for. Can you help me?
