Ok so if you think she’s bluffing about this being the end then stall. If she queries make up tangible reasons why the house shouldn’t be sold. Suggest it get rented to offset the mortgage. Check if there’s any break fee. Tell her you want to transfer to you and refinance and need time to make enquiries.
I hear you on how quickly things changed. It happens. I was looking at old sms from my XW and I got an ilu etc 2 hours before bd. 5 hours before I got an excited call saying she’d found a house for us to buy. It makes no sense so I’ve stopped trying to make sense and so should you.
You’ve stated your case to her about not wanting it to end. Will it be better or not to actually fight this? How will she see that? Will she be sitting at home and suddenly decide she wants you back because you’re now fighting for the M when you maybe didn’t during the M? In Australia we have a saying ‘leaving the porch light on for Harold Holt ‘. You need to turn the light off til shes ready for you to flick it on mate.
