I was once faced with a some what similar situation once, but it did not involve divorce. My friends sister had been dating a dude for a while, and they broke up out of the blue one day. The dude was a real douche, and my friend and his sisters family did not care for the guy too much. Her family was happy when they heard the news, and figured that this was the best time for her to finally move on. They thought that it would be cool I if could
start dating her, but my friend didn't like the
idea. So, being the good friend that I was I didn't ask her out. Long story short his sister
and the same dude got back together, and
got married. The family still does not care
for the guy, and my friend is always
apologetic for speaking his mind and me
agreeing to it. I regret not calling her up.
She's good looking, has a very good job,
and a very good person. If your intentions
are more than just doing the deed...I say go
for it.
