Set up another bank account, get a lawyer and have the divorce papers served while she was at work or with her family. Along with the evidence when she tries to deny said cheating. Then when her new boy toy finds out the money train stopped he stops seeing her. After a few phone calls from her saying it will never happen again state I know it won't baby; because I am not stupid. See you in court. Get divorced and live my life. Yes, you probably figured out this is what I did.
