I wouldn't worry about what people say concerning the time before dating. If you start getting serious then you should consider why you feel that way and make sure your head is in agreement with your heart.
man we have to do something about our borders....they let all kinds of foreigners in to take advantage of our natural resources ;-)
On the dating front, I would opine that considering where your respecvtive spouses are in their relationships, why not have a little fun? Keep it light perhaps....no strings attached....just try to gal and have some fun!
