Should I divorce my sheep husband due to his negativity and lack of adventure?

We have been together 18+ years, and at first he used to travel with me and have fun. However, since he retired at age 68, he just wants to stay home. I still work and see many friends and go out with them. My husband shops, cooks, cleans and gardens. He is always home. I am always out with my friends. When we are together I find him boring, narcissistic and critical of whatever I am doing. He doesn't care about what I am doing, but rather about his cooking, or garden or other home related activity. The past few years, I travel to Paris, France by myself to see my friends and also meet people while I travel. I would love to find a partner who enjoyed traveling and going out. Is there any future or should I cut my losses after 18 years? (I just turned 67, but look much younger; my husband is 71.)
