Do you think the guy is falling for you already? If so, tell him in a nice way that you are worried that your husband might not like this and it may lead to something else. But if it is really just about friendship, then you have to talk to your husband and let him know that you met a new a guy. Let him know that he still continues to communicate because of the friendship. If he is the jealous type of guy, you have to understand him and let him feel that your relationship is secured and that he can trust you.

Next person should enter a song title that starts with N.
