My mom is turning 60 and she wants to invite us all to a 5 day vacation for her birthday. She cannot go because she cant take vacation days that week and she also has a "trouble pet" that she cant leave and thats also the reason we can never go on vacations (unless someone would live in our apartment and goes well with the pet,and thats quite much to ask for) I said I would want to go and asked if it would be ok and she says she feels excluded and that she would never do that to me(go without me)

so now in an asshole for wanting to go and i would never stop her of going if roles were reversed so im just conflicted here....

Side notes We see her family alot more than mine We live together and in our early 30s We rarely do stuff without the other
