Step parents and responsibilities

[Fandabbydaisy]

I know this is different for everyone but I wondered others thoughts. I have a teen and a tween with my ex. Ex has been with gf for over a year. Children met her and have regular contact for the last 6 months. Recently my eldest has mentioned dad says tween can stay with girlfriend while teen and dad go to a hobby. Or dad says gf can take tween to his hobby. My thoughts are that she isn’t their parent and dad needs to manage it or I can be around if things overlap?? Dad hasn’t mentioned to me and obviously I think it needs discussing. Just wondering how others manage this as it’s all new…

I still don't quite get your problem - you think your ex should discuss with you / confirm with you that his gf taking the children to hobbies isn't burdening the gf too much...?

If that's what you're worried about (though it's a bit bizarre?), then worry not, I'm sure the gf has her own agency and voice and can speak up if it's all getting a bit much.

If you're just upset the kids spend time with another "mother figure", then you really need to let this go.
