wearing my engagement ring and promise ring

My fiancé has been my fiancé for almost two weeks now. So this is all very fresh and happy times for me. 
I've always worn my promise ring on my right hand ring finger. It came in handy plenty of times people tried to hit on me. We've been together for six and a half years and I've had my promise ring for four of those years. 
When he proposed, he told me "take your promise ring off, well put it in the ring box and then place it in a safe place when we get home" (we were in Disney). So I did that, so I could place my new beautiful ring on my finger and officially call the love of my life my fiancé! Later on, or maybe the next day, I asked to see my promise ring to compare them in size (it's weird how they look so alike. We obviously have a style lol).  He then tells me "don't wear your promise ring" I was so confused. I said "what? Why not?" 
"Because I hate that I bought you that one. I didn't get a great look at it when I bought it and it looks so cheap and fake", he said. And if you look at the picture closely, you can tell there's one tiny diamond in the middle and then a silver rim/halo type around it that tricks the eye into thinking it's bigger. The small accent diamonds are placed two side by side, and then a little post/stud next to it, also to trick the eye. He said if he had noticed it the first time he'd seen it he wouldn't have gotten that one. I don't mind it. A promise ring isn't supposed to be the most out of the rings your SO is going to buy you. it was and is still a token of his love for me. I want to wear the promise ring on my other hand eventually but he gets so upset about it. I guess it's his ego. Is this a normal reaction for him to have? Am I wrong for still wanting to wear it?
