Husband doesn't want me to have friends

So when we met I only had a couple of friends and rarely went out. Our relationship moved so quickly that him and I were spending every single day together that honestly I kind of neglected those friendships. We never really had a discussion about friendships besides the fact that we both agreed that clublife and going out often wasn't our thing. Fast forward we have several kids and we still spend every day together obviously as we are married. I have been feeling like I would like to have other married women friends. Someone to get my nails done with, go to brunch, shopping, etc. Just wholesome morning/daytime girl stuff. I brought it up to my husband and his reaction surprised me. He feels like having friends in a marriage is weird unless it's like a double date thing. Mind you he has friends out of state who he rarely sees but I'm not always present when they hang out. We've only been on a double date twice with his friends. They go to the gym, hang out at one of their house, etc. And I have no problem with it. I don't understand his mindset. He's also saying he has known his friends his whole life and he feels uncomfortable with me hanging around someone new. And I also feel he isn't really open to a double date situation either because he doesn't how interest in anyone who isnt already in his friend group. He thinks HE should be enough for me and he is. But he doesn't go with me to get my nails done anymore and he hates shopping. Can someone help me understand?

**Also this isn't divorce worthy to me** disclaimer because some people think it's normal to throw relationships away for every uncomfortable situation.
