I don't know if I can stay married to my husband

My husband and I have been together for 25 years and married for 17. I had one kid a few years ago. I've been with him all of my adult life. He's an amazing man. He's kind and caring. He takes care of me and our son. He's an amazing father and husband.<br><br>But... he's not the most intelligent man. I can't help but feel sometimes he's not fully there. I know that sounds mean, but I just don't know how to explain it. He's very simple, and he has the same interests as he did when we met. He doesn't like to try new things. He has the same 3 places he likes to eat. The only 2 movies he likes are Home Alone and A Christmas Story. He doesn't like to read. He only likes to play 2 video games, and he's been playing them now for 15 years.<br><br>I have tried to drag him out of his comfort zone, but he just isn't interested. I gave up trying to get him to change and decided to do my own thing. I read, I explore, I try new foods and hobbies. But I feel like I've outgrown him. I feel like I'm too good for him. I don't know if I'm happy. I love him for taking care of me and our son. But I just don't know if I can continue to live like this for the rest of my life. I know that I should divorce him, but I just can't bring myself to do it.
