I I celebrate a big birthday this time next year. DH and our best friends have discussed/suggested celebrating with my dream holiday which will involve 15 nights away. Daughter will be 19. She will be living at home attending our local uni and son will be nearly 15. Neither want to join us. We have good neighbours and my parents live 15 mins away. They are in their late 70s and early 80s so my son staying with them 100% of the time I feel is too much of an ask but I would hope they remain well enough to be there if needed. My sister lives 30 mins away too and is happy to be an emergency contact.
We have left the children for the night a couple of times and they are quite self sufficient and independent. WIBU to go? Feel a bit selfish.
