He's about 10 years older than me, busy, and somewhat mysterious. What do I do?

I'm almost completely divorced, separated for over 1 year now.

However, I meet up with this different guy sometimes. He's about 10 years older than me. We seem to get along great, but he's very quiet when I'm rambling cause I'm nervous as hell in front of him. I always want to talk to him and ask him stuff, and he knows it, but he's always busy and whatnot.
