I know almost next to nothing about the process, but I've been reading your story power.
I wonder about this part of the exchange.
Her: I'm going out Me: Ok, are you out for the night Her: I don't know Me: Ok I didn't know what to tell the kids when they asked for you Her: no response, grabs keys and leaves
Do you honestly don't know what to tell the kids? Really? To me that sounds like you are using the kids to try to get information from her. Of course she wouldn't respond to that. I suggest you stop using the kids as excused to get information. If you want to know, ask. If not then don't. I think it makes you look weak.
