I would be there initially, and then well, good luck, gotta run, look good, and made up, if he comes at lunch, make sure you have plans, after work, you are meeting someone for a drink or appetizers. In the morning, there is a brunch you have to get to or golf or whatever, just make sure you smell nice,, upbeat, and busy, and then gone. Lay some new underwear on the bed for him to see. Make him curious.
