I'm not a very jealous person. It all depends on what triggers it, I think. Some people just don't tend to be the jealous sort, and yet others are always battling it. So, there's really no reaction that is predictable across the board. Your guy's wife doesn't sound like the jealous type, and you seem surprised by that suggestion so I guess you aren't either. Everything seemed to have gone well. I wouldn't worry too much about "keeping jealousy at bay" if I were you. Being respectful, amiable, and caring should be enough.

Oh, oh, can't you see? Love is the drug for me.
