Reply #7: Dad must choose his sister or his son.

[lumberjack_jeff]

If he attends the wedding, he picked wrong.

The family wouldn't do this if dad were to tell them unequivocally where his loyalties lie.

That said, no amount of pressure from his ex-wife is going to make that occur. In fact, it's counterproductive.

My advice, after a messy and unpleasant family experience, write them off. The aunt isn't your family, and Karl is old enough to realize that she isn't really his family either.

You didn't really say how Karl feels about this. Judging from my own experience, I am often far more offended or hurt on my son's behalf that he is from the inherent meanness of NT's.
