First time post feeling lost and confused

I'd say don't overthink it or try to read into. If you want to see the kids Wednesday night, then do it. Mentally prepare yourself to focus on them only and politely look right through her if you notice her at all.

I 100% agree. If you want to see them, then take her up on it. Don't engage with a fight with her. Just treat her like a work colleague - polite but not overly friendly or rude.
