Is your Significant Other unattractive, not too smart, or have some other "limitation"? If so, why did you decide to stay with them?

I think it would be uncanny if a partner didn't grow, age, and evolve with you and the world around you. Nothing seems to stay the same. While one dimension may fade away, others emerge. If you are lucky, you get to grow old. Daydreaming about starting over, trying something new, and feeling young again is natural. At least with current technology, it is mostly just daydreams.
