Do your kids have any sort or schedule or structure in their lives? Plan stuff out, maybe use a shared calendar, but definitely you don't need to be talking to her all the time. It should be only emergencies that y'all would need to call each other. I wouldn't send her texts and photos like that. The child exchanges don't require any communication either. Just park in the drive and wave if your W is there. Let the kids walk outside.
And no, there's no purpose to telling your W right now how pissed you are at her. Just stop being her little buddy.
What needs of hers is she getting met that you were neglecting before? Have you thought about this much?
And for chrissakes do everything you can to be 100 times the MAN that this basement dweller OM is.

It is not things that bother us, but the stories we tell ourselves about things.
