Holding a poster's feet to the fire isn't attacking at all. It is pointing out what needs to be addressed and not letting the poster off easy. Sure, it isn't fun to experience to be on the receiving end of some really tough comments from the WAS. Yet, we've all pointed out one way or the other that Jon did have a role in this and could have defused this situation early on.
We all come here for input, feedback, and insights on how to handle certain situations. To me, Jon has been DBing for quite while and I've noticed that he tends to argue right back to W instead of validating her. That has been pretty common theme in most of Jon's threads. Then he has the gumption to blame W for how she reacts when he had instigated a lot of them by his poor choice of words, timing, and what not. He needs to figure out a way to break this cycle. It is up to him.
It goes both ways. Jon needs to decide how he can change and influence how the interactions take place between him and his W. I haven't seen much growth in this regard from Jon. If you would go back to his earlier threads, you'll see this very common theme and I am trying to HELP Jon here by pointing out this very same pattern here.
I think I've said all what I wish to say here in regard to Jon's tendency to assign all blame on W for things going south. If Jon wishes to continue shooting himself in the foot, then that's his choice.
