How do I deal with this without seeming like a right moo?

DP's ex has an infuriating habit of ditching on her weekends with DSD and leaving her with us whenever she's got something better to do. (They share custody 50:50 so there's no excuse, she gets as much child free time as DP does).

Anyway, DP agreed to have DSD next weekend even though it's not supposed to be our weekend with her. Fine I said, but I've got long standing plans with an old friend in the Saturday so count me out of any activities you might plan.

Then yesterday DP asks me when and where I'm meeting my friend next Saturday. I told him and he said 'cool i'll see whats going on round there that me and DSD can do' (sub text, while you're with your friend and we camera up afterwards).

This has pissed me off a bit. I made these plans ages ago before DSD was in the picture for that weekend. I feel like I should be able to honour them without having to accommodate her. Since I told DP the score when he agreed to have her.

I just want to have a long, lazy afternoon/possibly early evening catching up with my friend and not have to worry about leaving to get home in time for dinner and bed time. Etc. AIBU? And how can I say that to DP without sounding like a cow?

Why not just point it out? that whatever plans he's making, he has to remember that you aren't going to be available at all that day and won't be home until late so he has to be able to get her back home and everything.

Sounds perfectly reasonable to me. Just explain it to him how you have here. And maybe suggest that it would be great for your dsd to have all that one to one time with her Dad without you around?

I would just tell him, be honest and suggest that he has a nice day on his own with his dd.
