OK, the story so far.
I booked a weeks holiday with my 2 best friends in August of last year, knowing that I had 11 months to organise childcare whilst I am away. I told exH that I was going on holiday, so he would need to look after his children for a week. I assumed that given 11 months notice this would be acceptable. He agreed and said that should be fine.
Knowing that he conveniently forgets things occasionally, I have reminded him every few weeks since. He has now turned round and said that he is looking for another job (he worked for our family business until now) so he might not be able to get the time off work to have the girls.
Am I being unreasonable to think he is being a total dick?
