I am a single parent to ds17. I have had the next two weeks booked off and in the diary since January. Ds has a part time zero hours job. His father lives in a different part of the country and historically hasn't spent a lot of time with DS although DS has seen him for two weeks this summer during which he cancelled work shifts. Tonight ds informed me that he will be working Monday Tuesday and Wednesday next week ie right in the middle of my time off. This means that we can't actually spend time together going to places on those days as I had planned to do. I was a bit fucked off about this; however I started googling and have found a five day holiday abroad that I can afford that would get me back here on Wednesday and then we can have days out after that. Would I be wildly unreasonable to just go and book it? I want a break, I've been parenting solo for pretty much 18 years and I have both the time and the money. What do you think?
