Kids. I want them, but he's unsure.

Recently started dating a friend of mine. He never wanted kids, but before we started dating said he was unsure. I definitely want kids.

Typically I wouldn't date someone who isn't sure (what's the point in saying if it's doomed from jump?), but I adore him, and I think he's worth taking a risk.

I'm wondering how long I should give him to consider this before I call it. I want to give him ample time because this is a big decision, but I also don't want to commit too much of my time to something that isn't going to work.

I'm also a bit nervous that he'll say he wants kids, or even temporarily convince himself, because of how he feels about me. He's already stated that other than the kids bit, he could see himself marrying me. (I recognize this is all super fast, which is out of character for both of us. We call it Mach 1. Lol.)

Not sure it makes much of a difference, but he's 33 and I'm 28. He has one divorce on his record, and I broke off an engagement. Both were several years ago.
