Dealing with a possible lie

after finding out that my husband cheated on me for a year, she said she was pregnant. 1 week ago she said she miscarried but has not supplied any proof and when contacting the hospital she said she checked into, found out that she was never checked in. i gave my huband that information and began to ask questions about what he had seen concerning the pregnancy. this has left my husband conflicted because he does not want to believe that she would be capable of doing something like this. what i would like to know is if it is right to want to be given proof so that my husband and i can move on?

Yes!
