You are at the point I was at when I exposed to OMW, and because of her and OM's weird living arrangements (1000 miles apart) that didn't put the fork in the Affair, my further exposure of WW's STD to OM.
When I did those things I'd had enough and was at the point I didn't care whether my marriage ended or not.
I think you might be surprised at your WW's reaction. Sounds like to me that she thought she could just keep playing the game and you'd let it happen. Now that you've put your boundaries in place I'll bet she crumbles.
If she says to you again that the affair is over and agrees to your other conditions, ASK her how you two can work together to make sure no contact is in place. Once NC is in place she'll have to get through withdrawal before you can make any progress. Would you be able to take a longer vacation where you can ensure there is NC to help her get through the roughest part?
You might also be surprised if she doesn't commit by Sunday, that a few weeks or so go by and the reality of it hits her that she comes back with her tail between her legs.
If she does agree to NC, be prepared, it stinks.
