I have been living with DP and involved with his DC for 2.5 years now.
From about 18 months ago, I became the default for childcare if DP's ex was running late, had something on, and I now do school pick-ups in the week for them.
BUT she will not communicate with me about this? If she needs me to have them (as I'm the go-to), she'll message DP at work to message me and have me let him know and then let her know. She has my contact details, but she'll always message him to message me to ask and then report back.
It doesn't matter how urgently she needs me to watch them, she'll still contact him when he's working rather than messaging me.
I find this bizarre.
At this point, I feel as though it borders on rude that she wants (essentially) favours from me but won't ask me herself and doesn't ever communicate with me to thank me for jumping in?
Just seeking other opinions because it just seems so strange to me but DP doesn't see the big deal? I think he sees it as they're the coparents who deal with each other, so it makes sense just to communicate through them two?
I don't know.
