Need to vent

I feel like I'm crazy or sound stupid.

In September I had my first baby with my now fiance, we were looking at baby names for a long time until we finally agreed on one.. James. At first James felt so right for my son and I loved it but a month or so before giving birth I decided I didn't like it. He wouldn't listen to any other names and was so set on James. So I asked him if we see him after the birth and dont think he's a James if we could change it and he said yes. Then I had my son.. I said to my boyfriend that I didn't think his name should be James and he said we told everyone it was James, had people sign things with the name James and ect.. so I felt like I couldn't change it.. so my sons name is James. I HATE IT! I want to cry about it because I dont like my sons name to the point I hate to call him by his name. He's 3months old the 3rd and I have said his name maybe 3-5 times to him since he's been born. I hate to say it, I hate hearing people say it and I hate hearing my fiance say it. But its his name and there's nothing I can do about it but I resent my fiance so much now for making me name my son a name that I told him more than once that I didn't like. Am I wrong for being upset? Should I just get over it and hope it grows on me? I want to cry about it I'm so angry that I was basically forced into naming my son something I didn't want to.
