Neville,
1. I do not know all of the details nor am I a rav so I cannot condemn or condone their alleged actions.
2. Why were were you complaining about her giur before it was”cool”? Are you against accepting gerim? Are you a dayan?
Lesschumras, I heard about a case where the ger (a man) said that he would not marry a woman who would marry a goy. There is also a story about a goy who decided to keep Shabbat but carry his siddur to shul so as not to be chayav mitta. When his Jewish neighbor pointed out that there was an eruv he said “You rely on that eruv?”
