If a Jew is aware a non orthodox Jew did not marry a Jewish spouse but thinks she is Jewish by a reform conversion, can the Jew discuss that person’s drastic marriage?
This is a difficult question for a difficult situation; therefore it is difficult to answer, being that I don’t know the people involved. The general rule is that if you think that the person will listen to you then you should say something, but if it doesn’t look like the person will listen to you, then it is better to not try to convince them that they should divorce etc. In the event that you think that it won’t help them change anything, you still might want to mention to him as a piece of information, that her conversion is not recognized by the orthodox. This might help them and their children in the future.
