That's not really much of an age difference at this point and the fact that he's at a similar life stage and (hopefully) financially established are big pluses for you. (What does he do for a living btw?)
Age differences do matter as you get older but it's not the most important thing. My sister's husband was 14 years older and he just died at 69, leaving her a widow at 56 - but his death from staph sepsis of unknown origin was a random accident. The bigger threat to their long-term life together was always his intermittent alcoholism and his not always being proactive about his heath (although NONE of this had to do with his death from sepsis). If this guy is fit and active he likely is also attending to his health in other ways as well so the age difference shouldn't be a negative.
In fact, being younger you get to stay the "hottie" longer. I was 4 years older than my ex and although I think I was aging well, as he began to panic about his OWN aging, he apparently wanted to be with someone much younger so that he could pretend he wasn't aging.
Just try to make sure his account of the divorce is factual - we all know how many WASs paint their divorces as "amicable" when really they just abandoned their spouses without trying to do the work.
