Long story short I have been invited on a 5 day long term time holiday with a friend. Childcare/time off not an issue for me. However I feel guilty about leaving DD to go.
It's a non-kids holiday as we are going to a specific event in a city. Not really suitable for kids DD age and I am a lone parent so wouldn't usually get time like this.
So what I'm asking really is AIBU if I go on this holiday 
DD will have been on several holidays abroad already this year so will not have missed out holiday-wise (very lucky with having family abroad I am not flush with cash). Am I a terrible mum for considering it
