How do I respond to the kids. Do I ignore the comments about me delaying??
Separate the two issues - account access and kids.
First up, I would layout a schedule for him with the kids. Talk to the kids. One of them is 19 so really that R is between him and the 19 yo. As for the younger child, create a set schedule. Does the younger child have a cell phone? If so, I would respond to your H with..."here is the schedule for the kids. I will share this with them so that they are aware of the dates that they are scheduled to with you. Please contact them on their cells to confirm if you are going to pick them up on your scheduled days.
I would not ask again for the online access or at a min. request that again in a separate text/email.
You do not want it to look like you are holding the kids hostage until you get the online access.
Glad to hear that you will receive the money you need on Friday.
Peace, Eric
