I think this situation points to another means of defense... Seriously, remove the relationship properly before starting a new one. Just like avoiding "bad" parts of town at night, some things just up your risks. "
I was going to type that exact thought.
" Somehow I don't think this would have matter in this case since filing for divorce a few days before seemed to put the wife over the top. "
The actual filing of papers isn't the issue. It is that the guy had someone else in play for aparently a while and was still married. This is a major stupid move on his part and he was just asking for trouble. Play stupid games, win stupid prizes.
So, should he shoot or not? He set up the situation, it was up to him to follow through.
