Oh, call him already!!
My dad, who had been widowed for five years, was visiting friends in Texas (from MN) went out one night and talked with several women, danced with a few, was impressed with one, and didn't get her number but found out she lived 20 miles from him here in MN. My dad's not overly shy, but for some reason, just didn't take that step.
He didn't do another thing about it. One night he was watching TV alone (which he did WAY too much of) and out of the blue a car drives up and it is her and a girlfriend "just stopping by..." . They had a very nice eight year marriage before we lost my dad to heart disease. If she had waited for him to call, he would have died lonely.
Take a chance, call him. Make it casual and OK for him to say yes or no.
