I (21F) am planning to go on a trip to Disney soon in a few months and my mom doesn’t want me to go alone and wants me to go with someone. I have planned to go with my sister (20F) But she had let me know her Aunt has passed and could not come to which I’m fine with.
My sister agrees I should go by myself as I could have lots of fun without being tied down to anyone the whole week but I am worried if I go by myself my mom would probably be pissed even after I place boundaries down and let her know I will contact her regularly while I’m there. She has repeatedly made multiple attempts to make me reschedule but I have had my mind set on this for a while and I will not change the dates regardless of what she tells me.
How can I talk and express to her I would feel a lot better by myself on this trip to try new things and explore myself without having to feel like an AH and just going without a word?
(My sister is my half sister, we share the same dad but different moms)
