No, don't let down your morals for that reason. If you don't take a stand for what you feel and how much you except in relationship, you will except anything. I can understand the past is the past and we may have sleopt with other peolpe before you or you before him, but he shoul've told you no she wouldn't work because he had a past relationship with her. But now that you know, leave it in the past, move forward but have curtain standards for the type of person that you both will hire. Talk about it , write it down and if need be post the kind of person you are looking for, break it down, I need a nanny that is.........and I will not except..........It sound a little harsh ,but it's better to be up front on what you want. And have some questions that you would ask that would satisfy you! Keep open communication going with husband, don't let untrust come into your home. Both of you talk and come to an agreement on the kind of person that you both will have in your home, OK!
