If it was not knowing TTATT that held your marriage together then it was held together with lies.
Life is short, if she wants to be with other dudes and you you don't like it let her go. There is too much good stuff out there to be stuck in a situation that isn't beneficial to both of you. Its not fair to either of you. If you both start to learn to live honestly with who each of you really are, it may break up your marriage, but maybe you will find out that you can be friends and move on to find someone that will want to be with you exclusively without fear of punishment or reward of paradise.
Time to start being real.
