add me to the list, Mark. The vows are called that because they're vows. Supposed to mean something. May I point out however, that even if she is your sister, and you take her in at least for awhile, she is also another human being that while modesty is certainly a virtue, it means nothing when another is in need. So given the circumstances I really do think that that issue is a very insignificant one, and that NO ONE should criticize the effort.

My best to you and to your sister, and worth it or not don't let him get away with anything. See a lawyer to ensure she's protected. 28 years of investment means something too.
