As someone who's had a rough week too, just keep taking it a day at a time. These waves come and go. Good job telling her no though! Set those boundaries. If she's going to walk away, she doesn't get anything from you. If she's going to effectively dump you as her H, she gets none of the benefits of your company. She has to experience that loss fully. She has this idea in her head of how much better it'll be when she's gone. It seldom is and when that reality hits her like a cold bucket of water, then she may change and start committing to you again. Until them, remain strong. One foot in front of the other, one day at a time.
