Yeah, I think I'd say something, especially as you have a way to contact him without meeting up in person, so if he gets angry about it you don't have to worry. I'd point out what you said here. And, honestly, I don't think there's anything wrong with being a bit "ageist" about one's romantic partners. People who are vastly different in age are at different periods of their lives, have different life expectancies, and it would make a big difference if one expected to have children (a 45-year-old man can still have children, but it may be more difficult for him than it would for a 35-year-old, plus it will be harder for him to run around after them as they get older, and given natural life expectancies, chances are that he might die when they are still on the young side--and if we were talking the reverse, a woman presenting herself as 35 and really being 45-50, the fertility thing would be an even bigger issue). So I think it's fine to state that you were expecting somebody closer to your age and time of life, etc., and that you're not interested in continuing to date somebody willing to misrepresent himself in order to get dates. A little harsh, but it might make a difference.
