thanks again.
I have learned to be wary of strangers; I make my own friends.
When I go out with someone - it is not for the purpose of spending the evening with strangers. I think that he is afraid of waiters/waitresses poisoning the food or something if they don't like the customer (because he has said something to this effect).
He might have been experiencing some manicky behaviour (related to a recent significant experience in his life), and in some respects he has demonstrated poor judgment.
