proudjew83 – let’s put the halachic issue aside and look at it ideally.
the fact is that a person doesn’t marry a woman in a vacuum, and the reality is that you marry ‘into a family’. her parents are now your parents (in-laws), with all dinim of kibbud av v’eim, and other halachos that come with it. yes she might be frum and a great girl, etc etc, but the boy also has to now deal with a non-jewish father-in-law which may be a very uncomfortable and sticky situation which one doesn’t necessarly want to put himsef into ??????? (ideally).
