Some days are better than others

[EDF]

Been letting WW deal with her own car problems after her fender-bender. However, now it looks like the damage is extensive enough to be effectively totalled and not worth fixing, so she will need a new car.

I feel like it would probably be appropriate to leave her to do her own car research/shopping/financing, and leave her to handle dealing with the totalled car.

However, we haven't really split finances yet. While she hasn't expressed remorse yet, things with OM have seemed to be petering out and I was kinda holding the "separate finances" thing as a consequence for if she re-escalated things with him.

Any thoughts how I should handle the situation?
