DS1 came down with a vomiting bug on Wednesday, but recovered quickly. DS2 came down with it on Thursday morning but he had it much worse - couldn't keep anything down, being sick every hour. Friday morning 7am was the last episode of vomiting that I witnessed, he was tired and slept a lot on Friday which is pretty normal for after a tummy bug ime.
It's ex's weekend to have them (he usually has them every 3rd weekend for 3 nights) but I suggested that they both stay with me Friday night due to the bug and to avoid DS2 travelling in a car. Ex picked them up Saturday morning instead. On Saturday DS2 seemed much better, no vomit, still tired but happily playing with DS1.
I usually stay home on my "weekends off" but I'd planned a night away with a friend in London, had been organised for weeks, which I went to and got back a few hours ago.
Ex kept hassling me from 3pm onwards with texts saying how unwell DS2 was (he knew I was away). He's been violently sick again" "2nd bout of diarrhoea" "I'm bringing him back to yours I haven't got lots of spare bedding" "I won't be able to take DS1 to friend's party" "the kids just want to come home"
For context DS2 has vomited twice since yesterday and had diarrhoea 3 times.
I've come home feeling horribly guilty for not being here in the first place, even though I know that ex should be more than capable of looking after sick kids, I do it all the time without him.
So WIBU?
