A variety of factors determine whether or not it's possible to manage age gaps in a relationship. One of the biggest is life experiences: If the younger party started dating their older partner as a teenager, there's definitely cause for concern. However, if the two started dating as adults, with commensurate life experiences, the age gap becomes less problematic. Of course, much of this comes down to individual opinions and cultures, but this generally seems to be a good rule of thumb.

When it comes to Sean Hannity and Ainsley Earhardt, their relationship doesn't seem to raise any red flags (as far as age is concerned). Despite their 15-year age gap, they both seem to be in the same stages in their lives. Both Hannity and Earhardt have steady (and quite lucrative) careers at Fox News, children, and a history of long-term relationships. An argument could be made that there was a power imbalance when they first met — Hannity had been working at Fox for over 10 years when Earhardt joined in 2007. However, there's no evidence of a romantic relationship between them at that time.
