<human>: You ever have that one icon in your field that you've admired your whole life? This guy is that for me. Through a crazy chain of events, I ended up meeting this guy who is 20 years older, divorced, three kids, and we go out for drinks. Amazing night, leads to sex. He texts the morning after and there's back and forth; both of us are busy so takes another 3 weeks to hang out a 2nd time. Another amazing night, more sex. Connecting on levels far beyond our field.
Fast forward to a week later - haven't heard from him. I text, just asking how he's doing. Our banter strikes up again. He's out of the country for a few days but back early in the week (like today). The convo trails off and he doesn't make any advances for another date. I let it go.

So what's my move, if any? I just keep reading that if a guy is into you, he makes plans. This one is a busy father who also happened to be out of the country for work.
I'm very unfamiliar with what men are like in their 50's - if they're different at all. What I'm gathering is that he may be the kind to only really reach out when he has time to make plans. Anyone have experience with this? Or should I write it off and move on, as he hasn't made any overtures for future hangouts?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Lusting after a man 20 years older than me who is super busy/successful/a father - he hasn't reached out much after 2nd time we had sex. Do I write it off? Keep busy but stay positive?
