I was left playing with DH i-phone (I only have an old brick) when my finger hit email and the booking page for an easy-jet trip comes straight up with tickets booked for a ski-ing holiday in January. First I know about it! But apparently (despite a couple of calm but sarcastic remarks like "where's the email with our tickets") I need anger-management. Apparently in a "calm discussion" once DD was in bed, he hadn't booked a holiday, just a flight
that he could cancel but I know it is by invitation from friends to a particular chalet that has happened before.
I don't have a problem with him going nor do I feel I need to give "permission" but I do not like that I am not even informed or it is not discussed before when there are serious financial issues that we are not addressing and I feel guilty if I can't make the few clothes I bought in the summer last over the winter by layering. DH say regularly "We are not going to spend anything on the house until we can manage our spending better!" 
Also this is one thing in a series of not being told something. I guess I can be grateful it is just one ticket not two I don't know or were meant to find out about!
How would you react?
