AJ & McCall: Dating Age Gap Debate @8

Is there an age gap that is too large when it comes to dating? AJ & McCall think anything within ten years really isn’t that big of a deal, but what about past that for the Debate At 8? One of AJ’s exes just got engaged to a guy that is for sure over 50, probably even a bit older. His ex is only around 25. How does that even work?
