Question: What do YOU want it to mean? If you don't want it to mean anything, then shut it down and stop letting him cross some of your own relationship boundaries. Have you told your husband your suspicions or asked him what he thinks about this man's behaviour? I dunno, when some guy makes me wonder what his intentions are, since I'm married (happily but that shouldn't matter one way or the other as the marital status is the issue) then I don't allow any behaviour that makes me think it's anything beyond what I've always considered platonic interaction.
