I have been in that boat and can tell you that either way someone gets hurt. Either your husband for cheating or you for not taking care of yourself. If you do not go for it, you will feel better about it and if you do, then a divorce is a one of the many end results. I know what my vows say and understand the risks. I am just going to say that if you feel you can live withyourself afterwards, then by all means, please yourself.
