September and all participants of this thread.
When I read about the role playing idea a red flag went off for me but I havent said anything. I feel compelled to do so now.

None of us are trained professionals. We also don't have the ability to really be there for one another in a physical sense.

Going back to a sensitive time or experience while someone is "pushing buttons" "playing devils advocate" whatever you want to call it does not sound like a safe thing to me.

You would be opening yourself up to reading a post that can directly affect you and may even be harmful. While you have the boards there will be no one there to really help you should things go to far. There is no direct conversation so the person would know if what they are saying or doing was too much. Judgements could be misunderstood as honesty.

Also consider that the people involved must be commited and understanding. They may decide that they can't handle the pressure and back out leaving you to deal with it or they may decide that you aren't "playing" right. They may decide they know how and when you should do something and if you don't comply they walk out of it.

All these things leaving you open, raw and on your own.
I think the roll playing could be a dangerous game and no one needs to hurt more than they already do.
