Are you saying that Jesus would have allowed the woman at the well to partake in communion if she had married the man she was with?
;-)
I cannot speak for my Lord except to say that He said He has come to save all of us all we have to do is to ask and accept it. I cannot see Him telling one person no for a sin when we are all sinners. That would make Him a liar and He is not.
That is actually a complex question. Would she have married the man she was with after being saved? ;-)
