Opportunity has arisen for me to go away for 4 nights in feb with my mum. This would involve leaving DH and dd (10) and ds (5). DH can work from home for two days - the other two are the weekend. I do feel torn leaving the family but I have saved money that I have earned from overtime and my mum is 71 so I feel it will be quality, precious time spent together. DH is being a difficult and I feel TBH he is jealous. Am I being selfish?
