My dad married Nula 3 years ago. I (18M) was dad's only child and Nula had three kids Josh (18M), Kaitlynn (14F) and Rory (11M). We all get along fine but last summer there was a fight and a decision I made is something they're not really over.
Rory was diagnosed with cancer in May of last year and the hospital he was first going to suggested a specialist hospital in another state. Because of how long the treatment plan for Rory was my dad and Nula decided we should so our stepfamily wouldn't be separated for long periods of time.
Since I was about to start my senior year of high school and because all my close family are here I didn't want to move and I asked my grandparents if I could live with them. They said yes and we talked to dad. He told me he wasn't okay leaving me behind like that. I told him it was better for my education and for me personally if I could stay and I told him I would probably move back once I turned 18 that November anyway. My dad was like so you wouldn't stay the year and would rather risk your education more by moving after senior year had started than doing senior year somewhere else. I said yes. My dad gave in because he didn't like the idea of me moving mid year but he hated it.
Nula told me Josh was moving before his senior year too and that he wasn't complaining about it. I told her Josh and I weren't the same person and we didn't have the same experiences.
After the move dad and I would talk 9n the phone every few days. I flew out once for a few days and flew back home. Dad was supposed fly back for my birthday but it didn't work out. I haven't really spoken to the others much. Rory the most after dad because he was upset I didn't go with them. Nula's pretty much disgusted with me and now dad is expressing more and more frustration with me for not moving. He asked if I would move after graduation and I told him I was planning to stay which added to it.
The other day on the phone my dad told me it was just disappointing that I stayed when Josh didn't put up the same fight. He said he knows they're not my bio family and that I'm not close to my stepsiblings to see them as just siblings but he said it would have meant so much if I had stood by them and moved when everyone else did. He said it wasn't a move for shits and giggles which is why my decision is so hard to accept.
AITAH?
