I've recently fallen out with my girlfriend as when we went on holiday I spent 2 full days looking after her and her friends children on the beach whilst the two of them went shopping. I pointed out that this was an ideal time for them to spend quality time with their kids but got called spoilt for not getting my own way. They were more interested in shopping for rubbish than spending time together as a family, just tell me am I being unreasonable lol.
