Dinner group date?

On Monday at my dinner group I met this guy who seems really nice. He's an attorney and much older than me, but I could tell he was interested. After dinner he asked me out! I said yes. The next day he emailed me and called me.

His email: "I enjoyed meeting you last night, and would love to see you soon. I loved the JDate horror stories, and your fun personality. And we have several things in common too."

He's like, a grown-up!

I have been unbelievably busy and haven't had time to talk to him, will call tonight. I hope he doesn't think I'm blowing him off.
