Lee, First of all, please don't think of hurting someone physically, even if she cheated on you. It is not worth to do this and end up in jail again. She could be telling the truth that she had been raped or just making up a story so that you wouldn't think that she cheated on you. Just have a heart to heart talk with her and don't be judgmental. Ask her if she still wants to have a life with you. Because if she's involved with someone else, you cannot force yourself on her. She has a choice here even if she has 2 kids with you. Just remember that people have a change of heart and mind. They have their own reasons why they changed. I repeat, it's not worth it to harm another person on her account. Just try to improve your life and move on just in case she has someone else now. Take care.
