Husband is set on name choice

We picked a name for our baby back in October. Now I’m feeling undecided that it’s THE name. I’ve asked my husband a few times to browse if there’s any other names that he likes, but he has his heart set. He says things like, “I like his name” or “he already has a name”. I do like the name, but my problem is I’m a very indecisive person. Is anyone else in the same dilemma?
