STBXH has got himself a new job. He just told me that it will involve weekend work.
We have DC together and have them on a week-on, week-off arrangement and have done so for about half a year now. Over the last 4 weeks he needed me to cover him twice during the day and he has also asked me to cover childcare one extra evening so far, for the sake of his work. I am stubborn enough to sort my own shit out and ask friends/ professional childcare to cover me where needed.
I have a routine where I see my partner on weekends I don't have the kids and while he sees them regularly and they get on well, we do also enjoy our child-free time together.
STBXH was very unimpressed when he mentioned his new time commitment and I reacted by saying he'd have to sort it. Don't get me wrong, I love having my kids around and look forward to them being at mine every week. And I feel that i SHOULD say yes, I'll have them, because, well, they're my kids. But I also feel that if I did he'd take me for a mug, because he has always left me to do the hard bit (homeschooling while working from home, while he has now prioritised his work over them several times) and then collected them the second he came back.
My partner thinks I was right to not agree to this, but he is also childless and I don't know whether that skews his view a bit.
More for traffic than AIBU, what do you think?
