Saw your post and yeah, I've been through something similar a couple years back with an ex. Even if the person recants and says they don't want to proceed anymore, the Crown often decides to keep pushing forward with the
domestic assault charges, especially if they think there's still a decent shot at proving it happened. In my case, there weren't any major injuries or past issues, so eventually they worked out a peace bond thing where charges got pulled in exchange for some conditions like no contact for a bit and staying out of trouble. It avoided a record, but it wasn't instant just because she changed her story. Depends a lot on the details, like evidence and history.
