What would you do

So I'm 29 weeks pregnant and we have a 3 year old I also have a medical issue that is making pregnancy just generally harder and more painful this time around. My husband said about going to a festival in malta its in a few weeks he said about it months ago and told him multiple times I do not want him to go as its not fair to leave me at 30 odd weeks pregnant with a toddler whilst he goes off on his jollies any other time I'd have no problem. So I really though I'd made it clear how I feel and he tells me last night that his friend booked his tickets which is rubbish as had this friend been told he wasn't going he wouldn't of got tickets so I beleive they have been planning it behind my back for months and I feel so angry and hurt that he has zero consideration for my feelings, he started a new job and has been saying he can't take days off for scans/hospital appointments but yet has got time off for the festival. He also went for the job interview in secret and took the new job before even discussing it with me now I'm just stressing out whats next seens as he's been so good and keeping things from me
