My husband's older son has had Covid so hasn't been here for a while (usually have 50:50).
He's here tonight for the first time in over a week so DH is obviously looking forward to it.
We'd (me and H, hadn't spoken to DSS about it) made some mumblings about getting a takeaway and watching a film later on with DSS once our toddler was in bed.
My Mum has just out of the blue asked if she can have toddler tonight, he's at her house this afternoon and she's asked if he can stay over which is fine for us!
My friends are going out this evening and I want to go given the last minute child free night from toddler 
H is pulling his face because he thinks I should be prioritising family night with SS who hasn't been here for a while and I'm going out next weekend anyway (I am but with a different friend to something that was booked ages ago). I always feel pressure from H in this sort of thing, like he expects me to be excited to see his son or something.
It sounds like a lot but in general I barely ever go out, it's just so happened that I have two opportunities one after the other.
AIBU to go anyway and leave H and SS to a night in together? Surely that's nice for them anyway.
