To not let DD have the day off school tomorrow

[yafifo2462]

I'm prepared to be told I'm BU/insensitive but I'm not sure.

DD is 15, and she's been with her boyfriend since earlier this year. He was diagnosed with cancer not long after but DD has been supportive and has been seeing him as much as possible, messaging him etc which I have no issues with.

He went into hospital a few weeks ago for an op, he's stayed in longer than expected so DD hasn't seen him for a while as he didn't want her to see him whilst he was very unwell. He's now well enough to go home and he's due to tomorrow, I've had a message from his mum asking if DD can go and see him as he wants to see her. The issue is school, DD has said she wants to see him also but can't as she has an after school club so won't get home until late and when she can finally see him she won't be able to for long due to her needing to come home ready for school the next day. I've suggested the weekend but she's said she wants to see him tomorrow and she'll only miss a day of school and if she doesn't he'll be upset etc.

Now I'm second guessing myself and I'm wondering if I am BU and if I should just let her have the day off?

I doubt a further 6 hours separation while she is at school will affect their mental health when they have chosen not to see each other for a while already. At 15 the DD will be in her GCSE year, probably with mocks in the not too distant future (my 15yo DD is a week from hers, if covid hits again mock results can be used to help grade students). School is important and she's not being blocked from seeing him, most people are suggesting waiting until 3pm.
