Guys, would you be jealous if your girlfriend had a male best friend?

My husband has girls as friends he grew up with, and they interact like family. I have no issues with him enjoying his friends and would not dream of getting in between them. She was a little nervous about me when we first met and I told her my husband was a good judge of character so I had no issues. She wasn't having any of that and demanded that I go with them. We had a blast and she told me all of his secrets 🤣. Now she feels completely fine with popping over or calling him.
