I am an Au-Pair working for a single Dad and his child. It's a bit of a long story, sorry in advance if this is confusing.
So basically, the dad had been gone on a holiday for a couple of weeks, leaving his DC behind (upset, missed him terribly). He came back this morning.
He has already requested me to babysit the next two weeks (per mail, friendly, no problem), but yesterday he sent a message on WhatsApp saying I also needed to babysit tomorrow night. No question so I felt like I had to say "okay" (I am not good at saying no because I don't want to appear lazy)
Problem: My mum is coming for mother's day, not staying with us but in a hotel nearby, weekends are generally my time off and I don't need to ask if I can do stuff (agreement says occasional babysitting, tbh after two weeks already planned and given the fact that he just returned from being away for weeks I thought he wouldn't need me for that weekend as well). We had tickets to see a Ballett and so on. I managed to get a refund for the tickets and now my mum and I will take DC with us for dinner etc. and then take him home.
I tried to ask subtly if it was really necessary (like: "Could my mum at least come in the evening as she is coming for mother's Day, we had tickets etc.") and I know IWBU for not putting my foot down and saying no but he just has that sort of"authority" if you get what I mean. I talked to DCs mum (She's lovely and really tried to help) but she is not available and I really didn't want her to worry too much or pit her against her ex as they are doing a great job co-parenting and I also don't want them to think I don't take my job serious or don't appreciate it. I also feel guilty that I think "Ugh, now DC is tagging along", please don't get me wrong, I love them to bits but I had been looking forward to spending time with my mum and also they won't be in their best mood because they actually just want to spend time with dad. Of course we won't let DC know, we have planned a fab evening with pub dinner and a walk and an evening of board games back home but still
AIBU to be upset...
a) about him valuing his free time over mine (I have been working all the time he was gone so I didn't just have the time off)
b) about having to cancel the mother's day treat for my mum (She's a bit upset but understands and mostly feels sorry for DC)
c) on DCs behalf as they really missed their dad and are quite upset that he already leaves them with their babysitter after only being home a bit more than 24 hours
sorry if this is confusing with they/them but this could be outing and I really don't want any of them to know how much this actually upsets me because I just smiled and muttered "it's fine" and re-arranged my weekend because I am a weak people pleaser. Guess I just needed to get this off my chest
