Sorry to hear this has happened to you. Completely out of the blue behavior like this is not uncommon.
You say your marriage now feels like a mirage, or a facade. Do not take this too personal. This is a reflection on her life as a whole. It would have been as real as anything is to her while she was there. To her turning the page and moving onto the next chapter means blackening the past to validate her actions. Her version of the past will be revisionist with the true feelings of that time being overridden by her feelings of now. It may have felt like a sham to her now, but then it didn't.
To a pwBPD they live from one mirage to the next, they are constantly hoping to find solid ground in the next mirage, but they are not grounded enough to find it, so off they go looking for the next magical fix.
Expensive tastes are just another face of magical fixes.
