Guys in late 20s answer please? Can a guy of 29 really fall for a woman of 48?

Ok, I joined a dating club a couple of weeks ago and this guy started mailing me. He seems a very nice person and asked if it was ok to keep chatting with me despite the age difference. Admittedly, I look much younger than my age. He has told me 'you're nicer than the young ones'. People take me for 34 all the time. I said that's fine, we can chat and even meet for a coffee if you like as I have friends of all ages. So today, he has asked to meet me for a coffee and go for a walk. Now the thing is, I've a feeling we'll get on, however I think that he wants children one day. Would it be out of the question for us to fall for each other? What do you think? I mean, it couldn't work could it?
