My husband is a stepfather.
Would he be over the moon at an extra hour’s drive? No.
Would he do it, for a random play date? Well, if I really wanted him to - yes. But no, he wouldn’t want to.
Would he do it so she didn’t leave early from her best friend’s birthday party? In a heartbeat!
OP is coming across as somewhat scathing of the XW not thinking the 16yo is responsible - so I hope she wouldn’t then hypocritically say the 16yo isn’t responsible over the babysitting!
As I’ve said… it’s not that I think the OP is the worst parent in the world for not making this work. It’s that the “reasons” are a complete pile of shit!
I’m still trying to work out why the husband needs to take the non-starting 4 seater, and therefore can’t take all 4 children, instead of the family’s 5 seater.
Doubtless there’ll be some bullshit that OP needs the 5 seater for her own night out, because her vagina stops her operating the jump starter, and the £100K household income doesn’t stretch to a taxi for her.
There’s something off about all the - OP knows it, and that’s why she’s posted it.
I think the AIBU she’s scared to post as she doesn’t want to face the reality is, “AIBU to think my husband could be in any way flexible to help out my child?”
