I know exactly how you feel lc4. I don't know how our H expect us to react when something like that happens. I mean we suffered through a huge betrayal, and the pain we have to endure our H will never understand. But please don't beat yourself up for it.
Every derailment is a learning experience. I hope your H calms down and understands or at least attempts to understand how seeing the OW brought back those feelings. After all it's not like you asked for the A to happen or asked to run into OW. He needs to put himself in your shoes and wonder how he would feel if the tables were turned.
Good luck and my prayers are with you!! Big Hugs!!
