Need advice for a WW who left

[dwh15]

Quick general question. Since the big blowout on money last week, WW has been avoiding contacting me at all, and going directly to kids to set up plans for picking them up, etc. So far, it's worked out OK, but it just annoys me. Like she's doing this for payback. We don't have any court order but the general setup has been she takes them around 6 or 7pm every M, W, and F. Would it be advisable for me to send a text asking her to send info regarding the kids? Or just let her keep doing what she's been doing, and assume that they are mine until 7pm every night, and if that conflicts with her plans, oh well, since she doesn't bother to inform me.
