Boyfriend is upset over something small..

So the nee iPhones were released in September and it’s currently October 9th? And my birthday is in 10 days. October 19th. I was going to buy myself the new iPhone. I’m only paying what it cost to upgrade. I’m paying with my own money. My boyfriend is a little upset because he wanted the new iPhone too.. Is it wrong of me to get the iPhone? I guess I just want to make sure that I’m not being selfish.
