I would just worry too much about how he was coping to be able to enjoy myself.
Why though? Think about it. Why? Would he not bother or might he just not do things how you would do them? Sometimes women are their own worst enemies when they refuse to hand over the reins...
I went away for the week with a hobby group of mine. I loved every minute! Planned activities, workshops, pub every evening... I just reasoned that he was their parent as much as I was and he'd learn. I left a short list of simple things (like what time she usually had lunch/a nap etc but I didnt really follow a routine so it didnt matter) I just told him to do what worked best for them. And he did.
He was absolutely fine! He just genuinely hadn't imagined how quickly an entire day could disappear, how little you could get done whilst not having stopped.
In his head, I (and also he) would have plenty of time whilst she entertained herself or slept.
He even took to setting the alarm for 2 hours before she woke so he could get a head start and it made little difference.
Have to hand it to him though - he took it on the chin and had even arranged a 1st birthday party with family for her and made a cake for the day after I got back.
We worked together when I returned to get the house finished and he was really pleased he'd done it. He was a much better dad and husband afterwards.
We split up 6 years later. This is the first time I've really thought about it. Thanks for the nice memory 😊
