I have been looking for a movie but can not remember the title or the actors in it. I know it was about a woman named Susie q. She had 2 boys and was married to a dentist. She winds up divorcing him, having an affair with her cousin, becomes violent and abusive with the children and at the end of the movie she blows up her truck with her and her son's and the cousin in it. Can someone help me find the movie title please?
