I would remind her about the hard times you both went through, and that you were by her side through all her issues and turmoil, and how happy you have been since being 'free' together, and now this feels like she is separating from you, punishing you, and you don't deserve it. You have been her total rock this whole time and now it feels like she is burying you. Just be open with her about how depressed this is making you and you want the life you had known together back. Don't argue witness issues, she doesn't care if they're wrong. Appeal to her emotions. But it's still her decision and I hope you will support her either way, and she will probably even out over time, like others have said. The cong is happy to see her back now, but they will probably start neglecting her again and she's going to see how burdensome it is and remember what she likes about staying home with you.
