I think that is a very reasonable circle of people to whom to expose. You did what you felt you had to do to try to save your marriage, and you also followed what the Bible says to do.
The text messages were pretty compelling, and the fact she refused to end her "friendship" speaks volumes.
I do understand her pain at facing your family. But she's going to have to decide if running away from all that, or working on her marriage and repairing these relationships, is what she wants to do. Just let her know that if and when she is ready to return to the marriage, and end all contact with him, that you will defend her to anyone who has a problem with that!!
