Just calm down right now. Even if she did file, there are plenty of spouses here that have had the divorce dismissed. There was a poster here named Jayban that had his WW file as soon as he found out, but then she never followed up with it. He went to plan B and eventually his divorce case got dismissed in Texas. He moved to California and was thinking of eventually refiling there, but I haven't spoke to him in a while. The point is, that filing does not mean the end of your relationship. Likely the reason she is acting out is to "punish" you for exposure and to prevent you from further exposure. However, you already exposed to her command which is what she was afraid of.

The biggest factor on whether or not your marriage can be saved is what kind of person your WW is. Is she the hopeless romantic type that is going to bounce around from relationship to relationship and get married and divorced several times? Was this just an honest mistake of her being naive and letting a friendship get too close or is she a narcissist that only cares about herself. Only you know the answers to these questions. However, you won't find out for sure until she no longer has contact w/ OM and gets through withdrawal. Then you'll see your wife peek through. If she is still nasty and doesn't want to reconcile, she's just an awful person and you are better off without her. Move on with your life and choose more wisely next time. If she calms down and starts acting like your wife again, then you will have your opportunity to reconcile.

What was your relationship like before the affair? What were the circumstances of the affair. When did it start, how long were they physical, how long ago did he move, etc. The longer the affair, the more difficult it will be to withdraw from.
