Sorry, I don't have much experience on dating dads, so I can't help you out very much!
Although, I did have a date with one one time (and the only time! lol!). And I have to say that I'm with you -- I get worried about the ex-wife drama and the strange kid look (not that I don't like kids -- I may not have kids of my own, but I am an Aunt! lol). The guy didn't have any ex-wife drama (from what I could tell from him), but I think he probably still had a thing for her (digressing a bit, lol).
I don't think it's strange, though, to be in your 30s or 40s and have children. I've seen plenty of men's profiles where they're like, 32 and they're fathers already.
Try to relax about the date tomorrow. What I did during the time we communicated with one another (through email, phone, in person) was to take an interest in talking about his child and sharing with him a few stories about my nieces and nephews.
NOT that I'm trying to say you should FAKE taking an interest in knowing about his children...just TRY to show some form of interest. Because I know women who don't at all -- they feel it's not their kid, so why should they, you know?
Just wanted to share that with you.
Have a great time!
Try not to freak!!! My D is a single Dad and I have enough x-wife drama for five of us!!!!
Okay, since you girls are dying to hear about my date I'm sure...lol..I decided to post tonight and let you know how it went.
I'm glad your date went well!!
