Single men over 40, need your help here.?

Gone on 2 dates with a guy divorced 6 years, was married for 16, who is now 44. We talk daily and I've been open with things he's asked about my past (43, married 12 years, now divorced). He said his wife helped him realize who he was, but they got married too young, and that when he's asked other women he's dated about their pasts, he's found out information that "tainted" the relationship. I've asked for more info about his marriage and dating past, but he doesn't want to "taint" our budding relationship. Is this a good thing or a bad thing? Should I give him some time, or is this a red flag? We met on eharmony (b-t-w his age on his profile was listed as 38. He says it's an error in the eharmony system, but I've known him 3 weeks, and it's still wrong, so he hasn't called anyone about fixing it. Again, problem? Or am I reading in too much?)
